| 摘 要： | 基于对线性多输入多输出(MIMO)系统的自适应盲源分离和盲均衡的研究,为了能够有效恢复输入信号,提出了一种在MIMO系统中引入抖动处理技术的修正抖动符号误差恒模算法.仿真结果表明,该算法可以在仅已知输入信号统计量的情况下跟踪信道变化,并且有效克服多个均衡器的输出可能锁定到相同的源信号问题,抑制ISI和MUI,恢复所有发射天线的发送信息.

| Abstract: | Based on research of adaptive blind source separation and equalization for linear multiple input multiple output(MIMO) systems,a modified dithered sign error constant modulus algorithm(MDCMA) with dithering technique is proposed for MlMO systems in order to recover input signals.Computer simulation results illustrate the proposed algorithm can be adaptive to channel changes,overcome the problem that signals of the same input may be received by many outputs,repress ISI and MUI,and recover all inputs when onl... |
