摘要
该文提出了一种新的盲自适应多用户检测算法,这种算法的计算复杂度为O(NL),其中N为扩频因子,L为取样数据窗长度。仿真分析表明,该文提出的算法稳态性能好,收敛速度特别快,且能适应环境的变化,是一种较好的多用户检测算法。
In this paper, a novel blind adaptive multiuser detection is proposed, the computing complex of this algorithm is O(NL), where N is the spread grain, and L is the window length. The simulation shows that this algorithm has good steady state performance and it converges very fast, and can be used when the environment varies, so it is a very good multiuser detection.
