摘　　要：This paper presents an adaptive linearly constrained second-order least mean-square (LC-SOLMS) algorithm for interference cancellation in space-time block coded MIMO systems with fading channels. By taking mean-output-energy (MOE) optimization method, an adaptive linear detection algorithm was built up, which can suppress multiple access interference and noise. Simulation results illustrate that the proposed algorithm has great interference cancellation capability and faster convergence performance.This paper presents an adaptive linearly constrained second-order least mean-square （LC-SOLMS） algorithm for interference cancellation in space-time block coded MIMO systems with fading channels.
