摘要
文中首先介绍了基本的RLS算法,分析了RLS算法中的初始化系数δ和遗忘因子λ对RLS算法收敛性能的影响。通过仿真可以看出,在相同的信噪比下,不同的δ对应不同的收敛性能。而不同的λ对收敛性能也有较大的影响。
Basic RLS algorithm is described first. Initialization coefficient and obliviongeneare the two princripal fators affecting the convergence performance. The simulation result shows that the different initialization coefficient reveals different convergence performance at the same Sianal-to-Noise, and the forgetting factor also has a greater impact on the performance.
