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.

Dear Hiring Manager, First of all thanks for creating an opportunity. Hope you are doing well. I will not propose what the maximum Freelancer do. I dont believe in copy paste Cover letter. I read your project details, if you discuss with me or ask me or talk with me then you can understand i have the better experience the sector you are looking for. It’s true that i am new to Freelancer, before that I was on Other platform with top rated contractor. But it has wind down I close the account there and create the new profile to Freelancer. i have completed this kind of project more than 10 time. So I can assure you that i can complete your task perfectly. For more it will be better if we can discuss or ask me any question if you have. Looking forward from you. Thanks with best regards
