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. Platforms: Matlab

A MFSK channel with AWGN is simulated. The simulation is implemented as per the book Digital Communications by Proakis. Reed-Solomon coding is used to enhance the reliability of the system. Platforms: Matlab

It can be used also for computing the BER (bit error ratio) for different Eb/N0 in an AWGN channel.MSK stands for Minimum Shift Keying. Requirements: - MATLAB 7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris
