File Information
Description

This model implements a communication standard known as PSK31. The transmit portion of the model can either synthesize the PSK31 signal, or use real world signals that were captured as Wave files.

The receiver features include: Automatic Frequency Control, Automatic Gain Control, Symbol Timing recovery with a fractionally spaced Farrow interpolator, Decision Directed Carrier Phase Lock Loop, dbsk or dqpsk demodulation with FEC.
References are provided in the Model.

Required Products Communications System Toolbox
DSP System Toolbox
Signal Processing Toolbox
Simulink
Stateflow
MATLAB release MATLAB 8.2 (R2013b)
Other requirements Soundcard support for PC only, but these elements can be removed from the model to run on other systems.
