DS/EN 300726 V.7.0.2

Digital cellular telecommunications system (Phase 2+); Enhanced Full Rate (EFR) speech transcoding; (GSM 06.60 version 7.0.2 Release 1998)

active, Most Current
Organization: DS
Publication Date: 15 January 2002
Status: active
ICS Code (Telecommunications in general): 33.020
scope:

The present document describes the detailed mapping between input blocks of 160 speech samples in 13-bit uniform PCM format to encoded blocks of 244 bits and from encoded blocks of 244 bits to output blocks of 160 reconstructed speech samples. The sampling rate is 8 000 sample/s leading to a bit rate for the encoded bit stream of 12,2 kbit/s. The coding scheme is the so-called Algebraic Code Excited Linear Prediction Coder, hereafter referred to as ACELP.
