用MODEM来发短信，包括PDU的算法，较为详细！

调制解调器编程，用的是AT命令，一个很好的学习例子。-modem programming, using the AT command, a good learning examples.

该程序为QPSK解调程序，符号速率2M,采样速率为64M-The program procedures for QPSK demodulation, symbol rate of 2M, the sampling rate of 64M

利用MSComm控件，通过串口发送AT指令操作Modem。在2台计算机之间进行数据传输。-use MSComm control, sent through serial AT command operation Modem. In between the two computers for data transmission.

This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and block turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.-This a software runing on the Matlab. it is used in the channel coding simulation.
