The research interests of this project focus on radio frequency (RF)/baseband co-design for the fifth-generation (5G) mobile communication system, which is an interdisciplinary project. The unprecedented growth in the demand for reliable high-speed wireless communications in order to support multifarious applications and services, and the limit on radio resource and energy highlights the need for new promising transmission and networking techniques. Accordingly, the concept of 5G mobile systems was introduced in 2012, which is expected to have various advantages over the previous mobile generation, 4G (or called Long Term Evolution (LTE)), even though there is no transnational 5G development projects have officially been launched. Actually, the investigation on 5G attracts attention of government and industry all over the world, e.g., in UK, Europe, US, China, India and Israel. The performance aspects of 5G comprise, but not limited to the following issues: higher energy efficiency, higher system spectral efficiency, broadened network coverage, enhanced connectivity, and better quality of service (QoS). To be summarised, 5G mobile systems would work in a smarter and more efficient way. Key techniques suggested for 5G includes massive multiple-input multiple-output (MIMO), small cell and heterogeneous networks, cloud-based radio access networks, multi-hop, cognitive radio, millimetre wave transmission, etc.
However, in practice, the performance of all aforementioned techniques is related to the RF front-end design. Specifically, it is affected by RF impairments, such as high-power amplifier (HPA) nonlinearity, in-phase and quadrature-phase (I/Q) imbalance, crosstalk, antenna coupling, low noise amplifier (LNA) nonlinearity, phase noise, imperfect timing synchronisation and echo. In the case with RF impairments, the benefits of techniques nominated for 5G become not visible or cannot be achieved anymore. The research theme aims at investigating RF/baseband co-design for 5G mobile systems with RF impairments, which optimises the entire transmission mechanisms and brings a new view for the integrated design of wireless communications. Specifically, the objectives of this project are to figure out which kind of impairments has crucial influence on techniques employed by 5G and then propose feasible compensation scheme to mitigate the negative impact of the RF impairments or suggest a new RF/baseband co-design taking into account the 5G techniques.
