NXP Semiconductors claims the world's first LTE/HSPA/UMTS/Edge/GPRS/GSM multimode baseband platform, which forms the basis of a next-generation software-defined radio (SDR) system solution.

Powered by NXP's embedded vector processor (EVP), a DSP core, the solution achieves data transfer rates of 150Mbits downlink and 50Mbits uplink and supports multimode capability to cope with evolving mobile standards, particularly challenging for next-gen mobile terminal manufacturers.

The EVP-based modem architecture supports multistandard baseband processing with negligible area and power penalties. Though the specifications for LTE are being finalized, NXP is able to implement preliminary specifications today and update the multimode baseband as the standard evolves. Critical to this approach is the implementation of the highly parallel EVP to provide the computational resources for demanding MIMO and OFDM modem functionality. This software programmable platform will enable OEMs to develop their next-generation products quickly with on-the-fly changes to the core behavior of the modem during the critical ramp-up phase of the technology, enabling faster time to market and better performance.

"This is the first cellular system solution to use NXP's breakthrough EVP technology to support the entire GSM family of standards, right through to LTE," said Marc Cetto, executive VP and general manager, business unit mobile and personal unit, NXP. "The solution is fully compliant to the current draft of the 3GPP R8 standard, and was defined in close partnership with global operators, OEMs and infrastructure vendors. Using a software-defined radio approach, we can create silicon and system platforms that evolve as quickly as the industry does."
