摘要
文中讨论了使用自适应噪声对消抵制有色噪声的原理、特点，提出了在特定情况下 一种改进的对消模型及其原理，并结合ＬＭＳ（Ｌｅａｓｔ Ｍｅａｎ Ｓｑｕａｒｅｓ）和ＲＬＳ（Ｒｅｃｕｒｓｉｖｅ Ｌｅａｓｔ Ｓｑｕａｒｅｓ）滤波器的实现，给出了计算实例。
The principle and characteristics of using adaptive noise cancellation to eliminate colored noise are discussed in this paper.An improved cancellation model and its principle are proposed under some given environment.With the implementation of LMS (Least Mean Squares) filter and RLS (Recursive Least Squares) filter, the calculation examples are also given.
