Fourier Plane-Wave Series Expansion for Holographic MIMO Communications [PDF]
IEEE Transactions on Wireless Communications, 2021 Imagine a MIMO communication system that fully exploits the propagation characteristics offered by an electromagnetic channel and ultimately approaches the limits imposed by wireless communications. This is the concept of Holographic MIMO communications.

Novel Radar Waveform Optimization for a Cooperative Radar-Communications System
IEEE Transactions on Aerospace and Electronic Systems, 2019 We develop and present a novel minimum estimation error variance waveform design method. The method optimizes the spectral shape of a unimodular radar waveform such that the performance of a joint radar-communications system that shares spectrum is ...

IEEE Access, 2017 In today's increasingly rich material life, people are shifting their focus from the physical world to the spiritual world. In order to identify and care for people's emotions, human-machine interaction systems have been created. The currently available human-machine interaction systems often support the interaction between human and robot under the ...
