Resource Overview

Implementation of adaptive interference cancellation technique for Additive White Gaussian Noise removal, featuring two correlated noise generation methods - one with single random noise source and another with dual random noise sources. The program calculates signal-to-noise ratio improvement and mean square error gain after denoising, demonstrating algorithm performance through quantitative metrics.

Detailed Documentation

This document presents an adaptive interference cancellation method for removing Additive White Gaussian Noise (AWGN). The implementation includes two distinct approaches for generating correlated noise sequences. The first method utilizes a single randomly generated noise source, while the second approach employs two independently generated random noise components. Our MATLAB-based solution computes key performance metrics including post-processing Signal-to-Noise Ratio (SNR) enhancement and Mean Square Error (MSE) gain reduction. These quantitative measurements provide comprehensive evaluation of the adaptive interference cancellation algorithm's effectiveness in suppressing noise interference and improving signal quality. The core algorithm employs LMS (Least Mean Squares) adaptive filtering techniques to continuously adjust filter coefficients based on error feedback, ensuring optimal noise cancellation across varying signal conditions.
