摘要
本文在分析经典LMS算法在噪声对消应用中的不足之处后,提出了一种块状LMS算法和一次范数准则下自适应算法相结合的混合算法并作了相应理论分析,在此基础上构成了以TMS32010DSP芯片为核心的自适应噪声对消的硬件系统并取得了较好的实时对消效果。
A new adaptive algorithm in which Block-Least-Mean-Square algorithm is combined with Least-mean-Absolute error criterion is put forward with the support of the analysis result of LMS algorithm's unsuitablity for noise cancelling. The hardware and software designs based on TMS32010 DSP are also presented and good performance is get from real-time noise cancelling.
