Title |
Efficient FIR adaptive filter using DPCM and the sign algorithm |
Date |
1989 |
Description |
This correspondence introduces an adaptive filter structure that requires zero multiplications for its implementation. The primary input signal is quantized using DPCM, and the DPCM outputs are processed by a conventional adaptive filter. The filter coefficients are updated using the sign algorithm. Under the assumption that the primary and reference input signals to the adaptive filter are zero mean, wide-sense stationary, and Gaussian, we also derive theoretical results for the mean and mean-squared behavior of the filter. A simulation example demonstrating the usefulness of the filter, as well as verifying the theoretical results and comparing the multiplication free adaptive digital filter to the sign algorithm, is also presented. |
