摘要
在无线数据通信系统中,由于多径效应的干扰导致信号在传输过程中不可避免地产生码间干扰。为了能够补偿信道的这种非理想特性,以减轻信号的畸变,降低通信系统的误码率,在接收端必须增加均衡器。自适应均衡因其具有能够跟踪信道变化从而自动调节抽头系数的能力,因此成为通信系统中一项重要技术。本研究以FPGA为设计平台,以Verilog为编程语言,研究并实现了基于LMS算法的自适应均衡器。
Because of the multipath effect, intersymbol interference （ISI） is inescapable during data transferring process in wireless data communication system. In order to compensate the non-ideal characteristic of channel and reduce signal distortion and error-coding probability of communication system, equalizer has to be used in the receiver. Cause adaptive equalization can track the channel environment and antomatically adjust coefficient, it has become a critical technique in communication system. Adaptive equalizer investigates and implements is based on LMS algorithm on FPGA hardware platform with verilog programming language.
