Performance Analysis of Adaptive Noise Cancellation for Speech Signal
This is an incremental study comparing existing adaptive filtering methods for noise cancellation in speech processing, with no new method introduced.
The paper compared the effectiveness of RLS, LMS, and normalized LMS adaptive filters for noise cancellation in speech signals, analyzing performance based on SNR, MSE, and cross-correlation metrics with varying step sizes and filter orders.
This paper gives a broader insight on the application of adaptive filter in noise cancellation during various processes where signal is transmitted. Adaptive filtering techniques like RLS, LMS and normalized LMS are used to filter the input signal using the concept of negative feedback to predict its nature and remove it effectively from the input. In this paper a comparative study between the effectiveness of RLS, LMS and normalized LMS is done based on parameters like SNR (Signal to Noise ratio), MSE (Mean squared error) and cross correlation. Implementation and analysis of the filters are done by taking different step sizes on different orders of the filters.
