摘要
在通信系统中采用均衡技术是改善信道特性行之有效的方法,为此从时域均衡原理出发,讨论了基于LMS和基于RLS的自适应均衡算法,并利用Matlab对两类算法进行了仿真,从均衡前后信号的星座图、算法收敛特性以及均衡前后系统的误码特性这三个方面对两类算法的性能进行了比较。
The equalization in the receivers is the effective method to reduce intersymbol interference. Principle of the time-domain equalization is proposed. Adaptive equalization algorithms based on LMS and RLS are presented, furthermore the performances of the algorithms are compared from several factors, such as the convergence, the symbol error rate and the constellation.
