NTT DoCoMo, Japan, could launch a ‘Super 3G’ mobile service by 2009, delevering download speeds of up to 250Mbps and uploads of 50Mbps, reports TechRadar following a public demonstration of the technology in Tokyo this week. The improved data transmission rates were achieved using 4×4 multiple-input and multiple-output (MIMO) technology on an LTE (long-term evolution) network. NTT DoCoMo, which inaugurated the world’s first 3G network FOMA in October 2001, says only a software upgrade, and not a hardware based change, will be needed to roll out its ultra-high speed service.

picoChip has added Systems4Silicon as an approved design center for its picoArray multi-core DSP. Systems4Silicon has a highly experienced team, capable of supporting customers with PHY, MIMO, PA linearization and RF design issues for advanced air interfaces applications, and already has considerable real-world experience with picoChip technology.

“Systems4Silicon is experienced in interpreting complex systems such as HSPA and WiMAX 802.16e. Their understanding of these standards, together with comprehensive knowledge of our architecture enables Systems4Silicon to offer clear time-to-market advantages to our customers,” said Guillaume d’Eyssautier, CEO and President at picoChip. “We are pleased to have them onboard to support the growing picoChip customer base.”

“We are delighted to be recognized by picoChip as an authorized design centre,” commented, Dr. Paul Turner, Director of Engineering at Systems4Silicon. “These are exciting times. The performance of the picoArray opens up a new world of design opportunities for advanced wireless applications. Our deep understanding of optimal system partitioning and detailed knowledge of signal processing positions us well to support manufacturers looking to develop the next-generation of wireless systems.”

Systems4Silicon has significant expertise in researching and commercialising the newest wireless technologies. The team have worked on technologies for WCDMA (including HSDPA/HSUPA), WiMAX and 802.11n WiFi. Two areas of particular expertise are MIMO and PA linearization with adaptive predistortion (DPD)¡ªboth critical for the most sophisticated air-interfaces such as 16m and LTE.
