The two spreading rates 1 and 3 correspond to chip rates
The chipset includes the TMS320TCI100 DSP, the TMS320TCI110 receive chip rate
coprocessor and the TMS320TCI120 transmit chip rate
Taking center stage will be Analog Devices' SoftFone(R)-LCR chipset, a flexible, highly integrated solution for developers of 3G mobile terminals based on the TD-SCDMA Low Chip Rate
(LCR) air interface, which continues to gain momentum as one of the 3G technologies expected to be implemented in China.
A unique feature of TD-SCDMA, the ITU-T accepted worldwide standard for Low Chip Rate
TDD, is its ability to dynamically adjust the proportion of time allocated to the uplink and downlink communications during a mobile connection.
Importantly in completing the voice call ACT has demonstrated the ability to combine the voice codec and CDMA chip rate
processing into the SpectruCell multiple protocol wireless base station.
Moynihan will discuss technical details of ADI's SoftFone(R)-LCR chipset, a flexible, highly integrated solution for developers of 3G mobile terminals based on the TD-SCDMA Low Chip Rate
(LCR) air interface.
The TigerSHARC DSP is a telecommunications-optimized, programmable device with the processing and data throughput performance to handle both the chip rate
and symbol rate tasks required for voice and data channel processing.
