Lecture  Abstract

Massive  MIMO has been viewed as a promising PHY technical solution for 5G cellular  networks. The main challenge of using large number of antennas is the high cost  of radio frequency (RF) chains. Antenna switch enables multiple antennas to  share a common RF chain. It also offers an additional spatial dimension, i.e.,  antenna index, which can be utilized for data transmission via both signal  space and spatial dimension. In this talk, we present a Huffman coding based  adaptive spatial modulation that generalizes both conventional spatial modulation  and transmit antenna selection. Through Huffman coding, the transmit antennas  can be activated with different probabilities. The optimal antenna activation  probability is derived to maximize the Shannon capacity. When the input is  discrete QAM signals, the optimal antenna activation probability is derived  through minimizing symbol error rate. Numerical results show that the proposed  Huffman coded spatial modulation offers considerable performance gains over  conventional spatial modulation or transmit antenna selection.
