摘要: 本文提出了適用于MPSK調(diào)制的盲均衡算法及其改進(jìn)形式變步長盲均衡算法。計(jì)算機(jī)模擬表明,這種均衡算法及其改進(jìn)形式均具有良好的收斂特性,可保證通信系統(tǒng)連續(xù)工作而無需周期訓(xùn)練。但其誤碼性能略差于傳統(tǒng)的LMS均衡算法。

Abstract: The blind equalization technique for MPSK signals is analysed and studied. A new blind equalization algorithm and the variable step-size blind equalization algorithm are presented. Computer simulations indicate that the new blind equalization algorithm and its improved form have a good convergence performance, so the communication systems can work continuously and do not require to be trained periodically. -
