Communication DSP Algorithms, Architectures and Integrated Circuits
Spatial multiplexing multiple-input and multiple-output is an important technique for improving the transmission capacity of a communication system. The receiver must mitigate the interference between antennas and detect the transmitted symbols by processing MIMO channel matrix and detecting the constellation symbols. Our research designs hardware-oriented MIMO preprocessing and signal processing algorithms and architecture and implements by FPGA or ASIC chips.

Millimeter wave (mmWave) system is an emerging transmission technique to improve the reliability and transmitted quality for the future 5G communication systems. MIMO beamforming technique can use the RF phase controller to achieve high-resolution spatial transmission channel to overcome the problems of path-loss and high-correlation of the mmWave channel. Our research focuses on hybrid RF/baseband beamforming for the mmWave MIMO systems. The DSP algorithms/processors are designed to build up the optimal RF beam-forming phase array vector and baseband MIMO precoding matrix. This approach can reduce the RF chain number and the power consumption of the analog front-end for massive MIMO systems.

modulation (SM) is a single-RF multiple-antenna transmission technique.
The smaller RF-chain number and low detection complexity at the
receiver make it an energy-efficient modulation method for the massive
MIMO system. The targeted MIMO dimension amounts up to hundreds of
antennas and the transmitter and receiver. Thus, our research focuses
