Vinh Tran, PhD Candidate
Vinh Tran is a PhD candidate in the School of Electrical Engineering and Telecommunications at the University of New South Wales (UNSW). He received B.Eng. (2007) in Computer Science and M.Sc. (2009) in Information Processing and Communication from the School of Information and Communication Technology, Hanoi University of Science and Technology. Currently. He is currently associated with Australian Centre for Space Engineering Research (ACSER) and Satellite Navigation and Positioning (SNAP) Laboratory.
Vinh’s research focus is dynamically configuration and programmable baseband receiver design for multi-GNSS signals. He has developed a pipeline programmable baseband correlator that can dynamically configure to process 16 GPS L1 C/A, 8 BEIDOU B1I, 4 GALIELO E1 or 1 GPS L5/GALILEO E5 channels. Combining the advantage of the hardware interleaving technique and the proposed dynamically configurable MAV decimator, the proposed pipeline correlator implemented on the Xilinx Artix-7 FPGA reduces resources utilization from 15.2% to 94.6% and power consumption from 16.2% to 65.7% compared to the corresponding conventional digital correlator. Besides that, he also developed a hardware-based model that accurately evaluates the effect of the sampling frequency, front-end filter bandwidth, Doppler frequency, and the received signal to noise ratio on the correlation output as well as the Delay Locked Loop (DLL) tracking error. This result can be used as a guideline for sampling frequencies and coherent integration time selection for GNSS receiver design.
