Abstract 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 dccorrelating condition and can completely remove multiple-access interference. The simulation results show that the algorithm has good performance.
