This paper presents a new modified algorithm of 16 kb/s ADPCM. The modification is related to the adaptive predictor rather than the adaptive quantiser. The purpose of this modification is to reduce the nonlinear distortion introduced by ADPCM when a high data rate signal passes through it. The performances of standard and modified algorithms are studied using a QAM signal at a data rate of 9.6 kb/s. The simulation results show that the performance of modified ADPCM is better than the standard ADPCM.
