在瑞丽衰落 =信道下，对信号进行qPSK调制(qpsk for relaygh channel)

uwb高斯脉冲的产生程序，请大家参考给个意见(UWB Gaussian pulse of procedures, please refer to the comment! ! ! ! Thank you)

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.)

OFDM自适应资源分配时，我们知道遗传算法很常见，这里我们给大家编了一下遗传算法的代码，供大家参考(OFDM adaptive resource allocation, we know the genetic algorithm is very common here, we compiled a genetic algorithm code for your reference)

说明：  遗传算法的应用实例，包括一维函数最小值和多维优化bp神经网络。非常适合初学者。(The application examples of genetic algorithm include minimum value of one-dimensional function and multi-dimensional Optimized BP neural network. Perfect for beginners)

HDLC控制协议中CRC校验码算法代码，为CRC16，Verilog语言(HDLC Control Protocol Code in the CRC checksum algorithm code for CRC16, Verilog language)

说明：  用MATLAB进行AM调制解调的仿真实验 包含包络 加噪 调制系数等变量的影响(The simulation experiment of AM modulation and demodulation with MATLAB includes the influence of envelope plus noise modulation coefficient and other variables)
