Xinwei Telecom Technology has selected the PC203 from picoChip as the baseband processor in the latest revision of its multi-carrier wireless information local loop (McWiLL) basestation design. McWiLL is a Chinese-developed mobile broadband wireless access standard, optimized for extremely wide area coverage, which is being deployed for the 2008 Beijing Olympics. In the design, two picoChip PC203 devices replace nine conventional TI C6xxx high-end DSPs and two large FPGAs, dramatically reducing cost and power.

The McWiLL standard combines SCDMA's traditional use in narrowband voice, and adds nomadic broadband functionality. It is based on CS-OFDMA (combining the advantages of both OFDMA and CDMA), adaptive modulation and uses dynamic channel allocation, smart antennas, beam forming, and interference cancellation to improve reach and throughput. As a Xinwei-developed wireless standard, all the development has been done in-house in Beijing.

“Xinwei is a truly significant player and this is a good example of the advantages of our architecture over traditional DSP, and of our capability to power any standard,” said Doug Pulley, co-founder and CTO of picoChip. “This agreement furthers picoChip’s support for Chinese wireless development, and it is a testimony to the maturity of our architecture and tools that Xinwei has been able to develop such a sophisticated product so quickly.”

“The picoArray is a powerful device that can effectively tackle the extreme signal processing needs of next-generation wireless,” added Dr. Wen Bin, VP of Xinwei. “Designing with such an efficient architecture represents a significant step forward in our migration to deliver designs, easily, and at highly competitive price points.”
