The Files includ;The Filecy modulation and demodulation technique

Very simple simulation of modulation BPSK in simulink.For more information, visit: http://www.matpic.com

gmsk modulation of numerical data generated by a random source, the output of the modulator give two signals, only for demonstration, the first is gmsk signal and the other is gaussien frequency pulse shape

This model is an 8-ary modulator/demodulator based on Pulse Amplitude Modulation (PAM).You can change the Eb/N0 parameter in the "AWGN Channel" block to see the effect of the channel noise on the demodulated signal while the simulation is running.The input is a sinusoid with a frequency of 1 Hz.
