| Abstract: | For effectively supressing multi-access interference,a new multiuser detection method based on minor component analysis-constant modulus algorithm(MCA-CMA) was proposed.MCA-CMA is an algorithm with a Rayleigh entropy cost function,which is deduced from the traditional CMA error cost function.This paper simulated and compared the proposed MCA-CMA with the conventional LSCMA and LCLSCMA.Simulation results showed that the proposed MCA-CMA algorithm improved the performance in SINR and bit error rate etc dramat... |
