Performance analysis of DPCM codecs operating on adaptively frequency mapped 7.6 khz speech

Abstract

The performance results of the adaptive DPCM speech codecs which have been used in conjunction with an Adaptive Frequency Mapping system (AFMAP) are presented. The AFMAP preprocessor operates on a wideband speech (0.3 7.6 MHz) and compresses the speech signal into 0.3 3.3 MHz telephone channel. This signal is subsequently digized by DPCM codecs employing… (More)
