ETSI - TS 126 090 - DIGITAL CELLULAR TELECOMMUNICATIONS SYSTEM (PHASE 2+); UNIVERSAL MOBILE TELECOMMUNICATIONS SYSTEM (UMTS); LTE; MANDATORY SPEECH CODEC SPEECH PROCESSING FUNCTIONS; ADAPTIVE MULTI-RATE (AMR) SPEECH CODEC; TRANSCODING FUNCTIONS - V13.0.0; 3GPP TS 26.090 VERSION 13.0.0 RELEASE 13 Organization: ETSI
Date: 2016-01-01
Description: The present document describes the detailed mapping from input blocks of 160 speech samples in 13-bit uniform PCM format to encoded blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits and from encoded blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits to output blocks of 160 reconstructed speech samples.
ETSI - TS 146 060 - DIGITAL CELLULAR TELECOMMUNICATIONS SYSTEM (PHASE 2+); ENHANCED FULL RATE (EFR) SPEECH TRANSCODING - V13.0.0; 3GPP TS 46.060 VERSION 13.0.0 RELEASE 13 Organization: ETSI
Date: 2016-01-01
Description: According to this reference configuration, the speech encoder takes its input as a 13-bit uniform PCM signal either from the audio part of the Mobile Station or on the network side, from the PSTN via an 8-bit/A-law or μ- law (PCS 1900) to 13-bit uniform PCM conversion. The encoded speech at the output of the speech encoder is delivered to a channel encoder unit which is specified in GSM 05.03 [3].
TIA/EIA-136-210-A - TDMA THIRD GENERATION WIRELESS - ACELP MINIMUM PERFORMANCE - REVISION OF TIA/EIA-136-210 Organization: TIA
Date: 2001-04-01
Description: ., TDMA Cellular/PCS - Radio Interface - Enhanced Full-Rate Voice Codec, which is accompanied by a soft copy consisting of fixed point ANSI C code and a number of test sequences. The ACELP speech codec is used to digitally encode the speech signal for transmission at a data rate of 7400 bps or 148 bits every 20 ms.
TIA/EIA-579 - TELECOMMUNICATIONS TELEPHONE TERMINAL EQUIPMENT TRANSMISSION REQUIREMENTS FOR DIGITAL WIRELINE TELEPHONES Organization: TIA
Date: 1998-11-01
Description: These requirements apply to terminals that encode and decode analog signals in conformance with p-law PCM and 64 kbit/s as described in ITU Recommendation G.711.
