Performance Analysis of Acoustic Echo Cancellation Techniques

Mainly, the adaptive filters are implemented in time domain which works efficiently in most of the applications. But in many applications the impulse response becomes too large, which increases the complexity of the adaptive filter beyond a level where it can no longer be implemented efficiently in time domain. An example of where this can happen would be acoustic echo cancellation (AEC) applic...

Adaptive Noise Cancellation using Multirate Techniques

Abstract—This paper presents development of a new adaptive structure based on multirate filter and testing the same for deterministic, speech and music signals. A new class of FIR filtering algorithm based on the multirate approach is proposed. They not only reduce the computational complexity in FIR filtering, but also retain attractive implementation related properties such as regularity and ...

Recursive filter estimation for feedforward noise cancellation with acoustic coupling

The basic principle of feedforward noise cancellation for broadband active noise reduction is based on the availability of a reliable measurement of the noise source. Reliability is compromised in case the noise measurement is acoustically coupled to the actual active noise cancellation (ANC), as stability and performance of the feedforward compensation becomes ambiguous. This paper presents a ...

Acoustic Noise Cancellation Using Block Lms Filter in Matlab Simulink

In this paper, we use LMS filter and design a model with the help of Simulink using MATLAB 11a software. The effect of interference of acoustic noise in speech signals is the most common problem in speech processing. Acoustic noise reduces the intelligibility of speech signals by masking them. We need to suppress this acoustic noise for better communication. By using this technique, the acousti...

Wavelet Based Adaptive Filtering Algorithms for Acoustic Noise Cancellation

This paper prefers Acoustic Noise cancellation (ANC) system using Wavelet based adaptive filtering algorithms. The Acoustic Noise canceller is implemented using adaptive algorithms like LMS (Least Mean Square), NLMS (Normalized Least Mean Square),RLS (Recursive Least Square), and FRLS (Fast Recursive Least Square). The inclusion of wavelet based transformation in ANC reduces the number of sampl...
