bpsk调制信号通过rayleigh信道的误码率测量(ber of bpsk over rayleigh channel)

Least mean squares (LMS) algorithms is a type of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean squares of the error signal (difference between the desired and the actual signal)

说明：  此程序中将两个离散时间信号卷积，在数字信号处理过程中很有用！(conversion)

时频分析工具箱，需要加载路径到matlab里，里面包含了时频分析所用到的大部分函数(Time frequency analysis toolbox, need to load the path to the MATLAB, which contains the time-frequency analysis used by most of the functions)

用matlab实现的图像匹配，配有目标图片和程序说明(Implemented with the image matching matlab, with a target picture and description of the procedures)

用LS法估计的AR参数并用Cadzow谱估计子估计出信号的功率谱密度(With the LS estimation of the AR parameters and spectral estimation Cadzow child with estimated signal power spectral density)

第一步是计算输人信号单边功率谱密度（ESD）。使用快 ％速傅里叶（FFr）算法将信号从时域转换到频域。因为FFr算法的输出是离散谱，而这 ％里我们需要的是连续谱，因此需要引人不同的比例因子来实现从离散谱到连续谱的转换。 ％在第二步中，我们利用迭代算法计算出相对于特定阂值的ESD的最高和最低频率，从而 ％估算出被检测信号所占用的带宽。这种算法同时适用于基带信号和已调制信号。最后， ％在第三步中，我们给出了输出图形的原代码。(The first step is calculating the input signal unilateral power spectral density (ESD). The use of fast Fourier speed (FFr) algorithm for the signal conversion from time domain to frequency domain. FFR algorithm because the output is a discrete spectrum, which we need is a continuous spectrum, so the need for food of different scale factor to achieve from the discrete spectrum to continuous spectrum conversion. In the second step, we use iterative algorithm to calculate a specific threshold in relation to the ESD of the highest and lowest frequency, thus estimated to be occupied by the signal detection bandwidth. This algorithm applies to both baseband signal and modulation signals. Finally, in the third step, we give the graphical output of the original code.)
