Firstly, it discusses the principle of adaptive interference chancellor, including broad band signal and narrow band signal; Secondly, it analysises one common algorithm used in adaptive interference chancellor, that is, LMS algorithm and its anamorphosis algorithm especially normalized LMS algorithm pointing out their relationship. After then, the paper talks about the structure and reality of canceling broad band noise in narrow band signal and narrow band noise in broad band signal and gives it's result simulation analyzing the factors affecting the power of the algorithm. In the last party, it gives the hardware design and assembly language software design using TMS32OC3 1, including the result of simulating.

首先，本文讨论了自适应干扰对消的原理，并对窄带信号和宽带信号两种进行了分别分析；然后本文对自适应干扰对消中常用的算法—LMS算法进行了分析，同时也讨论了LMS算法的变形算法，尤其是归一化LMS算法，并指出了这些算法的相同和不同之处；此后，本文讨论了窄带信号中的宽带干扰对消和宽带信号中的窄带干扰对消的结构及实现方法并给出了住址的结果，分析了影响干扰对消效果的因素；在论文的最后，给出了用TMS320C31实现窄带信号中的宽带干扰对消的硬件设计和汇编程序设计，以及汇编语言程序的结果，并就此结果与高级语言程序的结果作了比较。
