Current Vacancies:

1. PhD Studentship in Broadband Millimetre-Wave Transceiver Architectures for 5G Cellular Communications

With the continuously increasing demands for higher data capacity, it has been growing interests in developing cellular systems to be operated in the millimetre-wave (mmWave) bands, between 30 and 100 GHz. The development of cellular systems in mmWave however faces significant technical obstacles. The propagation can be very poor and power efficiency is very low with the existing architectures and technologies. Linearity is another serious issue. New research breakthroughs will be essential to make cellular communication at mmWave frequencies possible. In this project, we are aiming to develop novel mmWave transceiver front-end architectures and related circuits and systems using advanced CMOS process and combining with the emerging GaN device technologies. In particular, the research will focus on power efficiency and linearity enhancement in power amplifier design and digital intensive transceiver architectures.

The project is fully funded by CONNECT starting in September 2017 for four years. The research will be conducted in the RF & Microwave Research Lab in collaboration with Analog Devices. Applicants should have Bachelors or Masters degree in electronic engineering with excellent background in RF circuit design and communication signal processing algorithms. Potential candidates should send CV and academic transcripts to Prof. Anding Zhu ( anding.zhu@ucd.ie ).

2. PhD Studentship in Digital Compensation Algorithms for Wideband Wireless Transmitters in 5G Cellular Communications

With the rapid development of digital integrated circuit technology in recent decades, modern CMOS technologies now can provide digital signal processing (DSP) capabilities at high integration density, low energy consumption and low operational cost. Applying digital signal processing to enhance the performance of "irreplaceable" and performance-limiting analogue building blocks has become a new design paradigm. For instance, digital predistortion (DPD) has become one of essential elements in the digital baseband to compensate the distortions induced by analogue power amplifiers (PAs) at RF frequencies in high power cellular base stations today. Digital assisted analogue design will play an even more critical part in fulfilling future system requirements. In this project, we will focus on developing advanced signal processing algorithms (using FPGA/SoCs) to enable highly power efficient and cost effective digital-assisted reconfigurable RF front-end architectures for 5G wireless communications.

The project is fully funded by CONNECT starting in September 2017 for four years. The research will be conducted in the RF & Microwave Research Lab in collaboration with Xilinx. Applicants should have Bachelors or Masters degree in electronic engineering with excellent background in digital circuit design and communication signal processing algorithms. Potential candidates should send CV and academic transcripts to Prof. Anding Zhu ( anding.zhu@ucd.ie ).
