说明： PSK31 Model with Symbol Timing and Carrier Recovery
(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.)

To install, unpack this zip file into a clean directory (eg c:\psk31model).
You will need MATLAB Release R2009B or Later. (it has been tested in 2012B)
Simulink
Communication Systems Toolbox Blockset (and it's dependent products)
StateFlow
Windows OS
The main model is psk31C_1.mdl. It is a self contained example in that it produces PSK31 signals
either from synthesis, or from recorded wave files of actual received signals. References regarding
this standard are provided in the model.
There is also a receive only model: PSK31C_R1. It uses the "from wave device" (PC soundcard)
to capture the PSK signals. You can connect a communications receiver to the PC audio port and
decode PSK signals.
If you are running UNIX or LINUX, you will need to edit the models to remove the Windows platform
sound card and wave file dependencies and simply use the synthesized data mode.
