关于通信系统的simulink仿真，包括基本介绍，数字信号传输，信道编码，OFDM方式，MIMO系统仿真(On the communication system simulink simulation, including a basic introduction to digital signal transmission, channel coding, OFDM mode, MIMO system simulation)

说明：  3. 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比。(3. Modulation demodulation and channel estimation in Rayleigh channel: (1) deduce the theoretical bit error rate performance of BPSK coherent demodulation in single-path Rayleigh channel, and draw the relationship curve between bit signal-to-noise ratio and bit error rate. (2) in single-path Rayleigh channel, please design a time-division guidance assisted channel estimation method, Simulink simulation, measure the bit error rate performance of BPSK, draw the relationship curve between bit SNR and bit error rate, and compare with the theoretical bit error rate curve.)

说明：  最简单的收发程序，可以用于超宽带测距，信道通信等等(The simplest transceiver program can be used in UWB ranging, channel communication and so on)

产生16QAM基带信号，成型滤波通过AWG信道，接收端得到误码率和星座图。(The 16QAM baseband signal is generated, the shaping filtering is passed through the AWG channel, and the receiving end obtains the BER and constellation diagram.)

说明：  用hspice写了一个做了16bit kogge stone四层点操作的树形加法器静态逻辑网表，所有管子的尺寸按照0.25u的尺寸设计挂上测试文件跑以后逻辑没问题，但是按照拉贝尔那本书上讲的关于逻辑努力优化的方法优化，在输入级加了两级buffer，只对最长路径支路尺寸优化(Use HSPICE to write a 16bit kogge made stone four layer tree adder static logic netlist, all pipe sizes according to the size of design 0.25u hang test file to run after the logic is no problem, but in accordance with the method of logic optimization efforts of Labelle's book about the optimization, plus two buffer in the input stage, only the longest path branch size optimization)

说明：  空间平滑music处理相干信号，相干信号的常用处理方法(Spatial smooth music processing coherent signal, coherent signal processing method)

OPNET上实现的原码，与卫星通信有关，有兴趣的可以下载(OPNET to achieve the original code, relating to satellite communications, are interested in can be downloaded)

一些关于bicm调制的代码，比较好的，希望对大家有用(bicm modulation)

matlab中fsk调制与解解调解调方式有相干与非相干解调哟 (matlab fsk modulation and the solution demodulation Demodulation coherent and incoherent demodulation yo)
