Career Summary

Biography

Shah Mahdi Hasan received his Bachelor of Science (BSc) in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology (BUET) in 2015. Currently, he is pursuing his Doctor of Philosophy (PhD) in School of Electrical Engineering and Computing at the University of Newcastle (UoN), Australia. He is conducting his research on developing fast and low cost algorithm to be deployed in next generation wireless communication systems.

He has 5+ years of experience in R&D (Research and Development) in both industry and academia. Prior to start his PhD at UoN, he worked with Grameenphone, a subsidiary of Telenor. He received Best Paper Award for his debut publication on stochastic geometric analysis of OFDMA based LTE-A networks at IEEE Communication Society (ComSoc) student paper contest in 2015. In the same year, a team led by him won Runner-Up position in Cadence Xtensa Design Contest for designing Adaptive Beamformer for Microphone Array in non-stationary noise. 

In UoN, he worked on parameter estimation problem in BiStatic Frequency Diverse Array (FDA) radar. Later, he worked on codebook design problem for uplink non-orthogonal multiple access (NOMA) systems. Specifically, he worked on designing robust and scalable Sparse Code Multiple Access (SCMA) codebook. These works were published in Elsevier and IEEE International Conference on Communication (ICC 2020), Dublin.

Currently, he is working on Dense Code Multiple Access (DCMA) sequence design problem. Also his work includes massive-overloading of grant-free NOMA systems. Several articles are under peer-review phase and rest of those are in development pipeline.    

His research interest include estimation theory, statistical signal processing, information theory and statistical learning.

Grant-access based legacy networks are unable to deliver Uplink (UL) dominated sporadic transmission of short packets with low signalling overhead, which are the requirements of Massive Machine Type Communication (mMTC). Hence, grant-free Non-Orthogonal Multiple Access (NOMA) techniques are more suited for mMTC. Due to the inherent sparsity in the user activity pattern in an mMTC system, the existing literature revolves around Compressive Sensing based Multi User Detection (CS-MUD) algorithms, which employ random or Zadoff-Chu spreading sequences for NOMA. In this paper we explore the utility of sinusoidal spreading sequences, which allow some non-iterative algorithms to be employed in the context of active user detection, channel estimation and data detection in a UL grant-free mMTC system. These algorithms do not need prior knowledge about the user behaviour statistics, noise statistics, and the level of sparsity in the user activity, which might be difficult to obtain at the Base Station (BS). We present a comprehensive performance and complexity analysis to assess the feasibility of our proposal. Extensive numerical trials demonstrate the utility of sinusoidal codes for mMTC.
