一种新的适用于多径信道的基于LMK准则的盲自适应多用户检测及其收敛性分析

In this paper, a new linear blind adaptive multiuser detection based on LMK criterion is proposed for synchronous DS/CDMA system over multipath fading channels. The new algorithm bases on HOS(High Order Statistics) and reduces complexity remarkably. The convergence of this algorithm is analyzed over multipath fading channel in the noise-free environment. In this case, the algorithm has global minimum point. On global minimum point, the algorithm satisfies decorrelating condition and can completely remove multiple-access interference. The simulation results show that the algorithm has good performance.
