One is the Linearly Constrained LSCMA （LC-LSCMA）, the other is the Preprocessing LC-LSCMA （PLC-LSCMA）. The two algorithms are compared with the conventional LSCMA. The results show that the two algorithms proposed in this paper are superior to the conventional LSCMA and the best one is PLC-LSCMA.展开更多

It first uses the signals received from every antenna to correlate with the conjugation of the DoA vector of the expected user, and then applies the pre-processed signals to the LSCMA. We simulate and compare the proposed algorithm with the conventional LSCMA. Simulation results show that the proposed algorithm is superior to LSCMA.展开更多
