说明：  仿真Alamouti 的 BER 性能曲线（QPSK 调制）(Simulation BER of QPSK Alamouti STBC with two transmit and receive antenna)

数字通信中的16QAM映射，采用格雷码编码，包括星座图的显示，简单明了清晰，由此可以退出64,128QAM的matlab编码(Digital communication 16QAM mapping, the use of Gray coding, including the constellation display, simple clear, it can be out of the 64,128 QAM matlab code)

说明：  信道估计的插值算法（中兴捧月）XXXXXXXXXXXX(Interpolation Algorithm for Channel Estimation (Zhongxing Holding Moon))

可用于无协议串口调试和标准Modbus调试。例案：单片机无协议通信、变频器通信调试、PLC及工业仪表通信调试。(No agreement can be used for standard Modbus serial debugging and debugging. Example case: no agreement on single-chip communications, Converters debug communications, PLC and industrial instrumentation communication debugging.)

AWGN信道的代码，实现简单易懂，用C写的(AWGN channel code is simple to understand, written in C)

qpsk的仿真以及根升余弦滤波器成形另外有误比特率的比较(qpsk simulation and shaping the root raised cosine filter)

在信号处理应用上的，求取一维信号曲线的盒维数(Obtaining box dimension of one dimensional signal curve)

雷达点迹关联与点航关联的matlab程序(Matlab program of radar dot correlation and dot correlation)

说明：  QPSK的MATLAB实现包括发送数据、QPSK比特映射、成型滤波、载波调制、载波解调、收成型匹配、IQ抽样判决、接收比特数据恢复8个模块(The MATLAB implementation of QPSK includes eight modules: sending data, QPSK bit mapping, shaping filtering, carrier modulation, carrier demodulation, shaping matching, IQ sampling decision and receiving bit data recovery.)
