This repository contains PyTorch implementation of 4 different models for classification of emotions of the speech.
LDPC MATLAB simulation using BPSK + AWGN modulation decoded using Sum Product and Min Sum Algorithm
This is Matlab implementation of modulation and demodulation of QPSK signals with added white Gaussian noise
Autoencoder-Based Enhanced Orthogonal Time Frequency Space Modulation
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.
Colored/White Guassian Noise Removal via Adaptive Thresholding in Curvelet Domain
Data Rate Change Algorithms for an Efficient HF Communication
Part of the pipeline process to denoise signals received in an L- Band Secondary RADAR
Sliding Filter for AWGN Denoising
Simulation of a simple noisy communication system
This is a MATLAB DCS (Digital Comunication System) Simulation.
Python simulation of BPSK/QPSK over AWGN with BER vs SNR analysis
MATLAB simulation project for ASK, FSK, BPSK, QPSK and 16QAM modulation recognition using AWGN, feature extraction, SVM and KNN.
BER vs Eb/N0 simulations for QPSK (4-QAM), 8-PSK (rectangular), and 16-QAM over AWGN. MATLAB CLI demo with exportable plots.
End-to-end MATLAB implementation of digital modulation (ASK/PSK/FSK/QAM) and channel coding (Hamming, Convolutional, Repetition) with BER simulation and GUI — IUT Digital Communications Lab.
Semester Project for course Introduction to Telecommunications at ECE - NTUA
MATLAB simulations covering channel coding, CDMA, OFDM adaptive bit loading, and LEO satellite link budgets. Analytical derivations validated by Monte Carlo.
