Channel Raylay, help me code matlab

基于高斯白噪声信道采用M-QAM调制技术的系统，分组错误概率与信噪比函数关系的matlab仿真程序(Gaussian white noise channel with M-QAM modulation system, packet error probability and SNR function of matlab simulation program)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

通过比较传统仅移相的波束与移相+理想延时的波束，来说明述S波段宽带阵列孔径渡越现象(To demonstrate the aperture effct of S_band windband array, this programe comparing the beam pattern of the traditional beamforming method "phase shifting only" with that of "phase shifting+ ideal delay".)

不同信噪比下的检测性能曲线，横轴信噪比，纵轴检测概率，随信噪比增加，检测概率提高。(Detection performance under different SNR curve)
