This repository contains PyTorch implementation of 4 different models for classification of emotions of the speech.

This is Matlab implementation of modulation and demodulation of QPSK signals with added white Gaussian noise

Autoencoder-Based Enhanced Orthogonal Time Frequency Space Modulation

LDPC MATLAB simulation using BPSK + AWGN modulation decoded using Sum Product and Min Sum Algorithm

Python coding examples for wireless communication systems. This includes currently the topics of modulation such as 4-QAM, BPSK (2-PSK) with an AWGN channel and also Rayleigh fading.

Data Rate Change Algorithms for an Efficient HF Communication

Part of the pipeline process to denoise signals received in an L- Band Secondary RADAR

Colored/White Guassian Noise Removal via Adaptive Thresholding in Curvelet Domain

Sliding Filter for AWGN Denoising

This is a MATLAB DCS (Digital Comunication System) Simulation.

Simulation of a simple noisy communication system

A PCM-Based Vocoder/Decoder, a voice codec software based on PCM of voice signals to send over data network, whose quantizer provides both mid-rise and mid-tread quantization techniques, and an encoder with both Manchester and AMI signaling, providing the concept of AWGN channel, in addition to regenerative repeaters.
