说明：  用窗函数法设计一个能对模拟信号进行滤波的线性相位FIR低通滤波器。抽样频率为 kHz，通带截止频率为 kHz，阻带截止频率为 kHz，要求阻带最小衰减 dB。为了降低运算量，所设计滤波器的阶数要尽可能的低(With the window method to design a filter to the analog signals of linear phase FIR low-pass filter. Sampling frequency is kHz, passband cutoff frequency kHz, stopband cutoff frequency of kHz, the minimum required stopband attenuation dB. To reduce the computation, the order of the filter designed to be as low as possible)

16QAM仿真系统，学通信实验必备，绝对有用。(16QAM simulation system, learning communication experiment must absolutely useful.)

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)
