A well-designed vocoder
can endure random packet loss of up to 10% with only minor degradation of speech quality.
CML also offers designers the CMX608, a vocoder
option without the integrated audio codec.
The performance advantages of CDMA vocoder
technology, combined with GSM technology on our patented multi-technology platform, offer a unique switching solution for converged communications," said Jay Salkini, TECORE's president and CEO.
We are proud to partner with CML to integrate our leading edge vocoder
technology within CML's mixed-signal IC's.
In this new phase of the program, BBN will develop a noise robust vocoder
operating at the ultra-low data rate of 300 bps.
Other features and functions include two-way Short Messaging Service (SMS) capabilities; simple and mobile IP; AT command interface; dual UARTs; analog audio; two RF connectors; high-speed packet--and circuit-switched data; and support for both 13k QCELP and EVRC vocoders
A comprehensive suite of vocoders
and concurrent support for VoIP over Ethernet and AAL5, as well as VoATM AAL1 and AAL2, highlight the rich feature set and flexibility that system vendors require to migrate to next generation wireline and wireless networks.
This will enable OEMs to download proprietary or commercial-off-the-shelf software for functions such as vocoders
, echo cancellers, speech analysis, data and fax modems, encryption, and many others.
GSM radio interface: TDMA and FDMA GSM frequency bands limitations of the radio interface speech processing, including hybrid vocoders
and the application of Forward Error Correction (FEC) reasons for controlling a mobiles transmit power and advantages of discontinuous transmission.
Other features and functions include two-way Short Messaging Service (SMS) capabilities; simple and mobile IP; CDMA UDP Passive Server; TCP/IP protocol stack; AT command interface; socket interface, dual UARTs; analog audio; GPS and RF connectors; high-speed packet and circuit-switched data; and support for both 13k QCELP and EVRC vocoders
All devices in the MSP family support PMC-Sierra's Voice Processing Module firmware that provides the necessary VoIP functions for high-quality VoIP services, including vocoders
SPIRIT's mobile voice engine includes echo and noise canceling, jitter buffer, PLC and vocoders
and helps mobile OEMs to quickly deliver mass products for the voice over Wi-Fi market.
