802.11n信道模型，文件里涵盖了802.11n的信道模型MATLAB仿真代码(802.11n channel model, the document covers the 802.11n channel model MATLAB simulation code)

QPSK的编译 设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(QPSK compiled Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK variety of modulation and demodulation mode corresponding to the main (sub-coherent and non-coherent) error rate statistics, and with the theoretical value comparison, a graphical representation of bit error rate and SNR relationships.)

说明：  通过matlab来实现带通滤波，可自由设置带通范围，滤波效率高，结果精确(Through MATLAB to achieve band-pass filtering, the band-pass range can be set freely, the filtering efficiency is high and the result is accurate)

根据流程图搭建并且仿真OFDM系统，画出输入输出的信号的星座图，计算误码率，改变抽头系数……(According to the flow chart, the OFDM system is built and simulated. The constellation diagram of the input and output signals is drawn, the bit error rate is calculated, and the tap coefficient is changed.)

模拟圆形阵列天线方向图，画二维天线方向图；(Simulation circular array antenna direction map, drawing two-dimensional antenna direction pattern;)

说明：  BOC调制的Matlab程序仿真及Simulink模型(Matlab program and BOC modulation simulation model of Simulink)

关于无线传感网络二维的TDOA定位算法，内容详细(TDOA, TOA and AOA localization algorithms for wireless sensor networks are detailed.)

说明：  通过串口解析MODBUS协议 读开关量型的输入信号 读保持寄存器上的内容 批量写数据到保持寄存器(Resolving MODBUS Protocol through Serial Port Input signal of reading switch type Read and hold registers Write data in batches to hold registers)

c#写的opc客户端，调用OpcDaNet.dll(opc client c# to write, call OpcDaNet.dll)
