Overview

The first stage of 5G deployment is already well underway, largely targeting users in the sub-6 GHz region of the spectrum. Although 5G makes provision for use of millimetre-wave (mmWave) frequencies, it is really the sixth generation of mobile technology (6G) where it is expected to see widespread adoption especially in user equipment. This will include V-band (57-66 GHz) and E-band (71-76 GHz, 81-86 GHz). In this context, combining higher frequency communications with multiple antenna systems, featuring dozens of radiating elements at the base station (or access point), is an extremely attractive solution to obtain very high data rates (multi-gigabit / sec). However achieving this at mmWave frequencies will require a detailed knowledge of a number of factors such as hardware impairments, wave propagation and channel characteristics to name but a few. In emerging wireless applications, real-time channel estimation plays a crucial role in system operation, including the beamforming process. In a standard mmWave wireless communication system, techniques such as analogue beamfoming and direction-of-arrival (DoA) estimation are used to determine the channel state at any given time. This is critical when the wireless environment is a high-mobility one, such as experienced on highways, high speed railway networks etc. The process of learning from such a wireless environment requires an array of mmWave antenna elements in the physical layer, working alongside with a series of algorithms in the computational layer. The physical layer architecture required to efficiently learn from a mmWave wireless channel is generally cumbersome due to a large number of antenna elements and the associated mmWave circuit components connected to each antenna element. Radio hardware of this kind is power-hungry, and typically has high insertion losses while also requiring a separate system for heat dissipation. To decrease the complexity of the radio hardware and realize an energy-efficient technology, innovative hardware and signal processing solutions are needed.

In this PhD project, which will be conducted in conjunction with BT, the successful candidate will have the opportunity to study advanced physical layer system solutions and signal processing algorithms for emerging mmWave wireless applications such as 6G. The proposed PhD study will be carried out in the state-of-the-art Keysight millimetre-wave research lab. The research lab is a part of the Centre for Wireless Innovation (CWI), located in the University's Institute of Electronics, Communications and Information Technology (ECIT). The successful candidate will also have access to the state of the art laboratories and expertise available at BT, as well as gaining experience of collaborative research between academia and industry.

The proposed research will involve:
• Carrying out a literature review of mmWave architectures used in 5G and candidate architectures for 6G, with an emphasis on beamformers and signal processing.
• Developing a good understanding of compressive sensing and compressive RF architectures (antennas, beamformers).
• Developing energy-efficient RF hardware solutions based on channel characterization and wireless sensing.
• Building novel signal-processing algorithms leveraging compressive sensing and machine-learning, with an emphasis on direction-of-arrival estimation for wireless systems.

Learning Outcomes

Course structure

There is no specific course content as such. You are expected to take research training modules that are supported by the School which focus on quantitative and qualitative research methods. You are also expected to carry out your research under the guidance of your supervisor.

Over the course of study you can attend postgraduate skills training organised by the Graduate School.

You will normally register, in the first instance, as an ‘undifferentiated PhD student’ which means that you have satisfied staff that you are capable of undertaking a research degree.

The decision as to whether you should undertake a PhD is delayed until you have completed ‘differentiation’.

Differentiation takes place about 8-9 months after registration for full time students and about 16-18 months for part time students: You are normally asked to submit work to a panel of up two academics and this is followed up with a formal meeting with the ‘Differentiation Panel’. The Panel then make a judgement about your capacity to continue with your study. Sometimes students are advised to revise their research objectives or to consider submitting their work for an MPhil qualification rather than a doctoral qualification.

To complete with a doctoral qualification you will be required to submit a thesis of approx 80,000 words and you will be required to attend a viva voce [oral examination] with an external and internal examiner to defend your thesis.

A PhD programme runs for 3-4 years full-time or 6-8 years part-time. Students can apply for a writing up year should it be required.

The PhD is open to both full and part time candidates and is often a useful preparation for a career within academia or consultancy.

Full time students are often attracted to research degree programmes because they offer an opportunity to pursue in some depth an area of academic interest.

The part time research degree is an exciting option for professionals already working in the education field who are seeking to extend their knowledge on an issue of professional interest. Often part time candidates choose to research an area that is related to their professional responsibilities.

If you meet the Entry Requirements, the next step is to check whether we can supervise research in your chosen area. We only take students to whom we can offer expert research supervision from one of our academic staff. Therefore, your research question needs to engage with the research interests of one of our staff.

Assessment

Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present write up their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.

This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.

The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.

Feedback

Supervisors will offer feedback on the research work at regular intervals throughout the period of registration on the degree.

Facilities

Full time PhD students will have access to a shared office space and access to a desk with personal computer and internet access.

Entrance requirements

Electrical & Electronic Engineering costs

There are no specific additional course costs associated with this programme.

Additional course costs

All Students

Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.

Bench fees

Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
