Cramer2Rao_Bound
对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)

exercise317_1
Plot the log-magnitude of the Fourier transform of the signal over the interval [0, π], using
a 1024-point FFT. The signal should be windowed with a Hamming window of two different
durations: 25 ms and 10 ms with the window placed at the signal’s center in each case. Show
the log-magnitude plot for each duration.

RELS
增广最小二乘的递推算法对应的噪声模型为滑动平均噪声，扩充了参数向量和数据向量H（k）的维数，把噪声模型的辨识同时考虑进去。最小二乘法只能获得过程模型的参数估计，而增广最小二乘法同时又能获得噪声模型的参数估计，若噪声模型为平均滑动模型，，则只能用RELS算法才能获得无偏估计。当数据长度较大时，辨识精度低于极大似然法。(Augmented least squares of recursion algorithm corresponding noise model for moving average noise, expanded parameter vector and data vector H (k) of the dimension, the noise model identification and at the same time into consideration. Least square method can only obtain process model parameter estimation, and augmented least squares method at the same time can obtain noise model parameter estimation, if noise model for the average sliding model,, it can only use RELS algorithm to obtain unbiased estimation. When the data length is bigger, the identification accuracy is lower than maximum likelihood method.)
