AIS信号（GMSK调制）2比特差分解调及其误码率曲线(2 bit differential demodulation and BER)

Cooperative MIMO matlba source code

说明：  S7200 通过modbus 通讯与多块表通讯 定时轮询(Reading multi block instrument timing polling)

说明：  利用粒子滤波器对目标进行状态的检测估计,并且展示了滤波后与实际值的误差曲线图(Detection and estimation of target state by using particle filter)

调试串口很有帮助，用windowsAPI编写，避免了com控件的局限性(help for serialport debug)

说明：  cpofdm信道模型仿真，通过仿真得到cpofdm信道模型的复杂度和在各种信噪比下的误码率(Through the simulation of cpofdm channel model, the complexity of cpofdm channel model and the bit error rate under various SNR are obtained)

modbus 详细解说，协议文档。。。,包括了function。。。(modbus detailed explanation of the protocol documentation. . .)

瑞利多径衰落信道仿真，jakes模型，有图(rayleigh fading)

(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.)
