Ma, Meng is an Associate Professor with the School of Electronics, Peking University, Beijing, China. He received B.S. and Ph.D. degrees in Electrical Engineering from Peking University, in 2001 and 2007, respectively. From January 2009 to January 2010, he was a visiting scholar at Commonwealth Scientific and Industrial Research Organization (CSIRO), Sydney, Australia. His research interests include signal processing in wireless communication systems, information theory, full-duplex system and physical layer technologies.

He has published over 50 papers in refereed journals and conference proceedings. He holds twenty patents in wireless technologies and networking systems. He has served in the Technical Program Committee of international conferences including ISCIT2010 and ICNC2017. He is the co-recipient of three best paper awards including the ICTCC09 conference, the CMC2012 conference, and the 5G and future network international workshop. He was invited as a visiting scientist to the ICT centre of CSIRO from 2009 to 2012.

Dr. Ma has more than ten research projects including NSFC, the National Science and Technology Major Project, the HongKong, Macao and Taiwan Science & Technology Cooperation Program of China, the Beijing Higher Education Young Elite Teacher Project, and etc. His research achievements are summarized as follows:

1) Co-Frequency Co-time Full Duplex (CCFD): CCFD is a promising technique for the 5th generation of wireless communication systems. He proposed many key techniques for improving the capacity of CCFD systems. He has applied 13 patents, and published 11 papers in this area. In 2014, he’s research team developed the first outdoor CCFD system with over 500 meters communication range. In 2016, he’s team developed the first CCFD networking system consisting of two cells. The BS receivers are equipped with antenna array to perform receive beamforming. By generating spatial nulls, the BS receiver can delicately mitigate the inter-cell interference from other BS transmitters.

2) Optimal linear precoding method for out-of-band power leakage suppression: Out-of-band power leakage suppression is a traditional research topic in wireless communication systems. He proposed an optimal linear precoding method to minimize the power leakage. The problem was treated as a matrix Frobenius norm minimization, and the optimal orthogonal precoding matrix is designed based on singular value decomposition. This method can further suppress the distortion of in-band signal by using the extra degrees of freedom in the optimized matrix.
