An Adaptive Algorithm for Small Noise Pairs and Its Hardware Implementation

Abstract

In this paper, after analyzing the shortcomings of the classical LMS algorithm in the application of noise cancellation, a hybrid algorithm combining the block LMS algorithm and the adaptive algorithm under the first-order norm criterion is proposed, and the corresponding theoretical analysis is made. The hardware system of self-adaptive noise cancellation with TMS32010DSP chip as the core is constituted, and a good real-time cancellation effect has been achieved.
