Description / Abstract:

This document serves as the interoperability specification for the Dual-Rate Vocoder employed within the TIA-102 series of documents. This document merges two previous vocoder standard documents, one published as TIA-102.BABA to describe a Full-Rate Vocoder at a gross bit rate of 7200 bps, and one published as TIA-102.BABA-1 to describe a Half-Rate Vocoder at a gross bit rate of 3600 bps. This document now describes the functional requirements for the transmission and reception of voice information using digital communication media described in the TIA-102 series of documents at either bit rate. This document is specifically intended to define the conversion of voice from an analog representation to a Full-Rate or a Half-Rate digital representation. The Full- Rate digital representation consists of a net bit rate of 4400 bps for voice information, and a gross bit rate of 7200 bps after error control coding. The Half-Rate digital representation consists of a net bit rate of 2450 bps for voice information, and a gross bit rate of 3600 bps after error control coding.

The voice coder (or vocoder) presented in this document is intended to be used in any equipment that requires an analog-to-digital or digital-to-analog voice interface. Specifically, mobile and portable radios as well as console equipment and gateways to voice networks may contain the vocoder described in this document. The reader is referred to the TIA-102 series of documents for additional information on the integration of the vocoder into the overall communication system.

The Full-Rate Vocoder is intended for use over a radio air interface providing 7200 bps for voice data plus forward error correction (FEC). The reader is referred to the FDMA Common Air Interface standard, TIA-102.BAAA, and other related standards for more information pertaining to the radio FDMA air interface.

The Half-Rate Vocoder is intended for use over a radio air interface providing 3600 bps for voice data plus FEC. The reader is referred to the Phase 2 Two-Slot TDMA Media Access Control standard, TIA-102.BBAC, and other related standards for more information pertaining to the radio TDMA air interface.
