MATLAB-Implemented ADPCM Codec with Algorithmic Enhancements
A comprehensive ADPCM (Adaptive Differential Pulse Code Modulation) audio codec implementation using MATLAB, featuring detailed algorithm explanation and code structure analysis.
Simulation of (2,1,2) Convolutional Code Encoder-Decoder
Simulation of bit error performance for a (2,1,2) convolutional code encoder-decoder in a Binary Symmetric Channel (BSC), plotting the corrected bit error rate versus channel bit error rate curve, with encoder generator polynomials g1=[111] and g2=[101]. The implementation involves convolutional encoding using polynomial generators, BSC channel modeling with crossover probability, and Viterbi decoding algorithm for error correction.
