研究了一种新的盲干扰抑制和多径抑制的自适应算法，并将其应用于时分多址（TDMA）蜂窝通信系统反向信道的天线阵列处理中。该方法是基于高阶统计（HOS）处理的基带矢量样本在天线阵列的输出。基于累积量的解决方案和标准的多变量最小二乘解决方案之间的相似性被利用，以获得一个有效的自适应算法的基础上的低秩处理架构。相对于传统的最小二乘法，该算法具有良好的跟踪和增强的识别能力。
A new adaptive algorithm for blind interference rejection and multipath mitigation is studied and applied to antenna array processing in the reverse channel of a time-division multiple-access (TDMA) cellular communication system. The method is based on higher order statistics (HOS) processing of the baseband vector samples at the antenna array output. The similarity between the cumulant-based solution and the standard multivariable least-squares solution is exploited to derive an efficient adaptive algorithm based on a low-rank processing architecture. The algorithm exhibits good tracking and enhanced identification capability with respect to traditional least-squares methods.
