| 摘 要： | 使用自适应信道均衡器来抵消数字传输系统中噪声和信道造成的影响。采用两种自适应算法:LMS算法和RLS算法,并对算法进行了仿真,分析了系统参数对两种算法性能的影响,最后比较了LMS与RLS算法的收敛速度。仿真结果与理论分析相一致,验证了自适应算法的有效性。结果表明,虽然LMS算法不如RLS算法收敛速度快,但算法简单,易于实现。

| Abstract: | Adaptive channel equalizer is used to offset noise and channel's impacts on digital transmission system. LMS algorithm and RLS algorithm are utilized and simulated. The system parameters' impacts on performance of the two algorithms are analyzed. Furthermore, convergence speed is compared between LMS and RLS algorithm. The simulation results are consistent with theoretical analysis, demonstrating the effectiveness of the adaptive algorithm. The results show that LMS algorithm is not as rapid as RLS algorith... |
