认知无线电 频谱分配。 颜色敏感分配方法 (Cognitive radio spectrum allocation. The sensitive allocation method based on the color of user fairness)

This is a Tongxunlu system,very easy. 小型通讯系统，DOS界面。(This is a Tongxunlu system,very easy.)

zigbee的一些基础知识，引脚及其相关协议等(basic zigbee )

对无线通信环境下的多径衰落和阴影衰落进行的建模。给出了一些仿真的建议(Modeling on multi-path effect and shadowing under wireless communication system. And this code gives some advice on simulation of these situation.)

AWGN信道条件下 汉明编码和格雷编码的性能仿真程序(Hamming coding and Gray coding performance simulation program AWGN channel conditions)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

协作通信中译码转发方式DF协作方式实验仿真主程序。(DF collaborative experiment simulation main program)

本程序是将串口实时接收到的数据，然后将数据进行曲线绘制。(The data received by serial port is plotted in real time.)

本程序计算了连续相位调制CPM的功率谱密度(The program calculates the continuous phase modulation CPM power spectral density)
