摘要 在常数模算法 (CMA)基础上 ,提出一种适合于多电平调幅、调相数字通信系统的基于离散余弦变换(DCT)域滤波的新型CMA盲均衡器 .计算机仿真结果表明 :该盲均衡器较纯粹的CMA均衡器具有更好的均衡性能 . Based on the constant modular algorithm (CMA), a new type of blind equalizer wit h filtering in discrete cosine transformation (DCT) domain is proposed for the amplitude- and phase-modulated digital communication systems. Computer simulat ions show that the performance of the proposed blind equalizer is superior to th at of the CMA equalizer.
