Discovery Channel Deadliest Catch

Implements soft-decision Viterbi decoding for a rate 3/4 code over an AWGN channel using Simulink.The Viterbi decoder block from the Communications Blockset is enhanced to optimally support punctured codes.The attached BERTool session file compares the BER performance as the number of bits are...

This program performs a Monte Carlo simulation of a coherent QPSK communication system and plot the error probability performance over additive whit Gaussian noise channel. The detection is based on correlation metric. Simulation is performed for 10,000 bits and measurements are made accordingly.

A fast vectorized implementation of the ncc that handles color (3 channel) images as well as gray level.The algorithm for colored images is based on the ncc formulation for vector valued functions.Note: A bug that I found in the normxcorr2 was also fixed here.

The MATLAB program simulates binary frequency shift keying (BFSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random...

The Principles of Ambiophonics*: 1.) Ambiophonics uses RACE* (Recursive Ambiophonic Crosstalk Elimination) to enable binaural listening 2.) The Speakers are positioned with a separation angle smaller than 20?*A* (called Ambiodipol) instead of 60?*A* used in stereo. No worries, in contrast to...

I'm actually having trouble with the equalization of the channel, because the doppler effect introduces phase rotation, which I don't know how to correct. If anyone could help me, I' d be really thankful.
