hua-FFT

bandpass filter inverter

该算法用于自回归输入模型，是一种迭代的算法。其基本思想是基于对数据先进行一次滤波处理，后利用普通最小二乘法对滤波后的数据进行辨识，进而获得无偏一致估计。但是当过程的输出信噪比比较大或模型参数较多时，这种数据白色化处理的可靠性就会下降，辨识结果往往会是有偏估计。数据要充分多，否则辨识精度下降。模型阶次不宜过高。初始值对辨识结果有较大影响。(The algorithm used for autoregressive input model, it is a kind of iterative algorithm. The basic idea is based on data to conduct a filtering processing, after using ordinary least square method to identify the data filter, and then obtain unbiased consensus estimates. But when the process output signal-to-noise ratio is larger or model parameters are too, this kind of data white processs reliability will drop, identification results tend to be biased estimate. Data should fully, otherwise the identification accuracy down. Model order time shoulds not be too high. Initial value to identification results have great influence on.)

Lfm信号的simulink模块，模拟的是10微秒的信号，已验证(Lfm signal Simulink module, analog signal is 10 microseconds, has been verified)

The simplest channel which we use in ideal case is AWGN channel and everyone knows that before starting siluation on the other part of the system we must simulate the AWGN channel.this is AWGN channel with a BPSK signal going through it and finally we detect the signal and plot BER vs SNR to compair with the theory.
