摘要: 該文基于 CLSCMA算法提出了一種新的盲自適應(yīng)多用戶檢測(cè)算法,這種算法適用于多徑衰落信道。這種多用戶檢測(cè)算法能很好抵消多址干擾和克服多徑衰落,算法的收斂性能和子空間自適應(yīng)多用戶檢測(cè)算法相當(dāng),而穩(wěn)態(tài)性能稍強(qiáng)于子空間多用戶檢測(cè)算法。因而是一種優(yōu)秀的盲自適應(yīng)多用戶檢測(cè)算法,具有一定的應(yīng)用和研究?jī)r(jià)值。

Abstract: In this paper, a new CLSCMA-based blind adaptive multiuser detection which can be used in multipath channel is proposed. Analysis and simulations show that the approach converges fast and has a good performance, so it is a good adaptive multiuser detection. -
