Description: With a 2-order AR model to generate a stationary random process s (n). Among them,,, can be arbitrarily selected. Accrue to the white noise variance. Received signal, the received signal requires filtering, the output signal. 1, given the length of the Wiener filter M, investigation costs and the relationship between function and SNR. 2, for a given SNR, the cost function and examine the relationship between signal to noise ratio. 3, do step prediction, the cost function with the filter length and variation of signal to noise ratio.
