Abstract This article deals with developing new modified algorithms of 40kb/s ADPCM. Beside the standard algorithm, three algorithms are developed to reduce the ADPCM distortion. The performances of all algorithms are evaluated with QAM signal at speed of 9.6kb/s. The outcomes demonstrate that the first proposed algorithm outperforms the other algorithms.
