Abstract

Tugnait's multi-input multi-output inverse filter criteria (MIMO-IFC) using either second- and third-order or second- and fourth-order cumulants for blind deconvolution are extended to those using second- and higher-order (/spl ges/ 3) cumulants. Next, a blind maximum ratio combining (BMRC) method using the MIMO-IFC is proposed. Then a blind equalization algorithm for multiuser DS/CDMA systems in multipath channels is proposed using the proposed BMRC method and MIMO-IFC. Finally, some simulation results are provided to support the proposed algorithm.

基于HOS的MIMO逆滤波准则和盲最大比组合用于DS/CDMA系统的多径均衡

Tugnait使用二阶和三阶或二阶和四阶累积量进行盲反卷积的多输入多输出反滤波准则(MIMO-IFC)扩展到使用二阶和高阶(/spl ges/ 3)累积量的准则。其次，提出了一种基于MIMO-IFC的盲最大比组合(BMRC)方法。然后利用所提出的BMRC方法和MIMO-IFC方法，提出了一种多径信道下多用户DS/CDMA系统的盲均衡算法。最后，给出了一些仿真结果来支持所提出的算法。
