MATLAB code for Interference Cancellation of Speech Signals using Adaptive Filters

My aim is to cancel the interference and noise occurred in a speech signal when sent through a wireless network.

We have to modulate the speech signal at the source using Quadrature Phase Shift Keying (QPSK) modulation and pass it through the transmission channel where the speech signal encounters Log Normal Shadowing Path Loss, multi-path Rayleigh Fading which introduces Inter-Symbol Interference (ISI) to the signal. We also add Additive White Gaussian Noise (AWGN) to the signal. The interference and noise present in the received signal is then suppressed by using adaptive filters. We should use Least Mean Squares (LMS) Algorithm, Normalized Least Mean Squares (NLMS) Algorithm, Affine Projection Algorithm (APA) and Recursive Least Square (RLS) Algorithm in these adaptive filters for achieving our objective.

I have attached the speech signal file which you will use in this project. If you want, you can select a portion of that speech signal for simulation.

I have attached the adaptive filter model which you will use it in the simulation.

I have also written what type of MATLAB outputs I need along with the code in the uploaded document.
