Abstract: | In this paper we investigate methods of improving the performance of a finite impulse response (FIR) adaptive delta modulation digital filter (ADMDF). These include modification of the ADM step size adaptation algorithm, coefficient optimization, and the reduction of computational complexity. Compared to the FIR ADMDF of Sunwoo and Un 1], the improved filter yields better performance by approximately 4 dB and requires significantly less computation time. |
