英国赫瑞瓦特大学射频（RF）和无线通信研究博士后招聘

The Institute of Sensors, Signals and Systems (ISSS) is a multidisciplinary research centre at HWU. Its research clusters focus on National Strategic Priorities, including 5G (and enabling technologies), robotic, renewable energy, and advanced manufacturing. The Microwave and Wireless Communication Group, currently consisting of more than 10 faculty members. Leading a number of high-profile projects on signal processing, radio frequency (RF) subsystems, SatCom and wireless channel modelling, the group will provide a suitable platform for the postdoc to collaborate and grow. Facilities available for the project include: far-field and near-field anechoic chamber, 4-port Keysight VNA, VSG, VSA (all up to 40 GHz), 4-channel high-speed oscilloscope (20GSa/s), USRP-based 10-by-10 MIMO testbed, millimetre wave base station and terminals, and a suite of licensed simulation software packages, e.g. CST, HFSS, ADS, and LabView.

The research associate is expected to carry out the first systematic study of the physical-layer wireless security under the energy awareness context. The energy penalty of the current physical-layer security solutions will be recovered without compromising security performance. This ambitious object is achievable when a co-design approach, involving transmitter architecture, digital baseband, RF frontend and signal waveforms, is employed. This will require major innovations that currently lie beyond state-of-the-art, which include (a) system architecture- and modulation-aware artificial noise (AN) synthesis; (b) non-linear power amplifier-friendly AN synthesis; (c) digital/analogue hybrid modulation and precoding security scheme; and (d) system-level demonstration of physical-layer security solutions.

This research programme will be highlighted through two high-impact practical demonstrators, a real-time wireless high-definition video secure wireless transmission in laboratory multipath environment using a bespoke designed physical-layer air interface. The power efficiency improvement will be sufficient to recover the power penalty suffered in the current benchmark physical-layer security solutions. It is also planned to integrate the develop security technology onto commercial WiFi and 4G-LTE base-stations.

The post is available for 24 months.

Applicants should hold a PhD in a relevant area of Electronic Engineering or Physics or related subject (or a thesis submitted by the start date of the project); have experience with microwave and RF subsystems and must have proven academic ability and a demonstrable high level of technical competence in experimental science and the analysis/modelling of the results.
