There are three programmable vocoding rates: 2,050 bps, 2,400 bps or 2,700 bps and when combined with the embedded FEC, the IC provides an overall bit rate of 3,600bps.
Also integrated into the BCM 1101 are three analog CODECs capable of supporting both narrowband (8 kHz) and wideband (16 kHz) sampling, which in conjunction with wideband vocoding will enable IP phone networks to deliver higher fidelity voice transmission than PBXs or the Public Switched Telephone Network (PSTN).
If digital signal processing, vocoding, encryption, and explosion in cellular traffic volume weren't enough to frustrate cellular intercept, here's one more challenge: the existence of numerous, incompatible "standards" throughout the world [ILLUSTRATION FOR DIAGRAM 1 OMITTED].
This second edition differs most notably from the first, published in 1985, in its addition of several ideas and techniques that have since gained greater prominence, such as phase vocoding, granular synthesis, and physical modeling.
Variable rate vocoding also allows for lower bit rates during speech pauses.
bandwidth optimization - adaptive multi-rate (AMR) vocoding, tandem-free operation via peer-to-peer IP switching, voice activity detection (VAD) and bundling, in addition to standard features such as frequency hopping, enable operators to increase the productivity of scarce spectrum;
There are 3 programmable vocoding rates: 2050bps, 2400bps or 2700bps and when combined with the embedded FEC, provides an overall bit rate of 3600bps.
When deploying this system in remote or rural areas, the switching and vocoding functions can be moved closer to the base stations while maintaining a central Mobility Manager and home location register.
Historically within our target markets, equipment designers have had very little choice in terms of standard IC products for high-quality, low bit-rate vocoding applications and have had to pay high initial licence fees and ongoing royalties to use available technology.
ASE 2 vocoding technology is a key enabler of reliable communications anywhere, anytime among troops across all military branches.
