Abstract :
This paper addresses the problem of adaptive noise cancellation in a multi-channel system. The proposed canceller is a recursive system, based on the Least Mean Squares filter (LMS). This method is analyzed by simulations and experimental results are given. Specifically, it is shown that this technique can improve the accuracy of ultrasound ranging and positioning systems using multichannel receivers.
