摘要
在对统计特性未知的信号进行噪声消除的应用中经常需要使用自适应噪声对消法.LMS算法是应用最为广泛的自适应算法之一.本文对LMS算法的DSP硬件实现进行了研究,并在TMS320C6713 DSK上实现了基于LMS算法的自适应噪声对消.实验结果表明,LMS算法的计算复杂度很低,且在有确定参考源的情况下采用自适应对消算法能够有效地去除噪声.
The method that is often used to cancel noises mixed in characteristically unknown signals is the adaptive noise cancelling method.The LMS algorithm is one of the mostly used methods.The implementation of LMS algorithm on DSP hardware is studied in this paper,and the adaptive noise cancelling algorithm is realized in the TMS 320C6713 DSK.It is shown by the experiment that the calculation complexity of LMS algorithm is very low,and the noises can be removed efficiently by using the algorithm.
