A/D和D/A转换器模型 对串行和并行输出的8位A/D和D/A转换器进行仿真，转换值范围为0到255，转换采样率为1次/秒。 (A/D and D/A converter model, serial and parallel output of the 8-bit A/D and D/A converter to simulate the conversion values range from 0 to 255, change the sampling rate of 1 times/sec.)

time-invariant degradation models and stationary signals and noise, the classical Fourier domain Wiener filter, which can be implemented in O(N logN) time, gives the minimum mean-square-error estimate of the original undistorted signal. For time-varying degradations and nonstationary processes, however, the optimal linear estimate requires O(N2) time for implementation. We consider filtering in fractional Fourier domains, which enables significant reduction of the error compared with ordinary Fourier domain filtering for certain types of degradation and noise (especially of chirped nature), while requiring only O(N logN) implementation time. Thus, improved performance is achieved at no additional cost. Expressions for the optimal filter functions in fractional domains are derived, and several illustrative examples are given in which significant reduction of the error (by a factor of 50) is obtained.
