此程序用matlab编码，可以生成随机骨料，适用于有限元分析。。。。(This program is progressed by matlab, which can generate the concretebone. It can be used in finte element analysis.)

(1)建立DQPSK调制和解调 SIMULINK仿真模型，评估其在AWGN信道和瑞利衰落信道下的误码率性能（画出信噪比变化时的误码率曲线）； (2)基于（1）建立的SIMULINK仿真模型，分别在AWGN信道和瑞利衰落信道下发送一个实际音频文件，在接收端实时播放出来((1) the DQPSK modulation and demodulation SIMULINK simulation model is established to evaluate the bit error rate performance under the AWGN channel and the Rayleigh fading channel (the bit error rate curve when the signal to noise ratio changes). (2) based on the (1) established SIMULINK simulation model, a real audio file is sent under the AWGN channel and the Rayleigh fading channel respectively, and it is played on the receiving end in real time.)

这段程序是相干光通信系统的仿真机，可以用matlab来仿真相干光通信系统，具体的参数可以在代码里面自行修改。(This program is a simulation machine for coherent optical communication systems. Matlab can be used to simulate a coherent optical communication system. The specific parameters can be modified in the code.)

在光纤通讯仿真中，产生QPSK，16QAM，64QAM信号，并添加激光相位噪声和自发辐射噪声(In optical fiber communication simulation, QPSK, 16QAM, 64QAM signals are generated, and laser phase noise and spontaneous radiation noise are added.)

16QAM信号 64QAM信号的产生和分析，星座图，频谱，功率谱(6QAM signal 64QAM signal generation and analysis, constellation, spectrum, power spectrum)

这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性： 1. qpsk/16qam/64qam映射、解映射 2. OFDM调制解调（循环前缀，FFT等） 3. 非整数采样时刻多径时延的多径信道 4. Rayleigh或者Rician多径信道 5. 信道的连续时变（非block fading） 6. 线性插值信道估计 7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)
