Description: 一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.

Description: MATLAB program for OFDM generation and reception
This is a simple MCM communications system. The code is pretty self-explanatory. Here I have not used the cyclic prefix.
Transmitter End:
1. Generate random serial data with M symbols (RANDSRC will do this)
2. Perform modulation (4-PSK = QPSK for now)
3. Serial to parallel
4. IFFT
5. Parallel to serial
Receiver end
Just opposite of transmitter end.
