A Structure and Algorithm of Wideband Blind Equalizer Based on Subband Decomposition Technique

  • 摘要: 高速宽带无线通信中,多径传输信道可能导致几百个符号间的相互干扰,这使得接收端的线性盲均衡器的收敛速度极其缓慢。基于子带分解技术,该文提出了一种适合于高速宽带无线传输的盲均衡器结构及算法。该结构将子带分解技术和全频带的子卷积方法有机结合在一起,明显地加快了高速宽带传输条件下线性盲均衡器的收敛速度;同时通过对接收数据进行降低速率的并行处理,该结构还能减小运算复杂度,有利于工程的实时实现。仿真实验结果验证了文中提出的结构和算法的有效性。
