Listing of Communication in Scripts

This Simulink model simulates the entire transmission and reception of voice data of a traffic channel for GSM (TCH/FS)over a multipath fading channel, and it calculates the BER of the received signal..

Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-point access to the multi-rate filter design tool.

These are two M-files 'fourier1' and 'fourier2' The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing the number of terms included in the summation will improve the signal shape.

As a part of package Simulink there is a communication channel model "Binary Symmetric Channel". There are random errors in this model. However errors normally are packages in real channels of communication and I have developed such model of a channel.

While working with a histogram we may need to detect a peak or crest of the histogram.But the histogram contains a number of local minima & maxima which makes the histogram extremely uneven.While detecting a peak or crest we are intended to detect the global peak or crest.

random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range. The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and a histogram of the spectral content.
