This document serves as the interoperability specification for
\nthe Dual-Rate Vocoder employed within the TIA-102 series of
\ndocuments. This document merges two previous vocoder standard
\ndocuments, one published as TIA-102.BABA to describe a Full-Rate
\nVocoder at a gross bit rate of 7200 bps, and one published as
\nTIA-102.BABA-1 to describe a Half-Rate Vocoder at a gross bit rate
\nof 3600 bps. This document now describes the functional
\nrequirements for the transmission and reception of voice
\ninformation using digital communication media described in the
\nTIA-102 series of documents at either bit rate. This document is
\nspecifically intended to define the conversion of voice from an
\nanalog representation to a Full-Rate or a Half-Rate digital
\nrepresentation. The Full- Rate digital representation consists of a
\nnet bit rate of 4400 bps for voice information, and a gross bit
\nrate of 7200 bps after error control coding. The Half-Rate digital
\nrepresentation consists of a net bit rate of 2450 bps for voice
\ninformation, and a gross bit rate of 3600 bps after error control
\ncoding.<\/p>\n
The voice coder (or vocoder) presented in this document is
\nintended to be used in any equipment that requires an
\nanalog-to-digital or digital-to-analog voice interface.
\nSpecifically, mobile and portable radios as well as console
\nequipment and gateways to voice networks may contain the vocoder
\ndescribed in this document. The reader is referred to the TIA-102
\nseries of documents for additional information on the integration
\nof the vocoder into the overall communication system.<\/p>\n
The Full-Rate Vocoder is intended for use over a radio air
\ninterface providing 7200 bps for voice data plus forward error
\ncorrection (FEC). The reader is referred to the FDMA Common Air
\nInterface standard, TIA-102.BAAA, and other related standards for
\nmore information pertaining to the radio FDMA air interface.<\/p>\n
The Half-Rate Vocoder is intended for use over a radio air
\ninterface providing 3600 bps for voice data plus FEC. The reader is
\nreferred to the Phase 2 Two-Slot TDMA Media Access Control
\nstandard, TIA-102.BBAC, and other related standards for more
\ninformation pertaining to the radio TDMA air interface.<\/p>\n","protected":false},"excerpt":{"rendered":"
