Libraries Designed to Facilitate Rapid, Low-Risk Migration from 2G to 3G in the Chinese Wireless Market

Motorola has released its first TD-SCDMA module library for the MRC6011 Reconfigurable Compute Fabric (RCF) device. This module enables infrastructure baseband modem processing for the expanding wireless infrastructure market in China, which operates according to the TD-SCDMA mobile radio standard. The MRC6011 provides wireless infrastructure vendors with the flexibility and processing power needed to deliver base station platforms for next-generation wireless networks. Motorola's RCF library code kernels for TD-SCDMA are designed to tackle the most complex processing step of TD-SDCMA development - the joint detection uplink processing task.

"Motorola's RCF technology and the TD-SCDMA standard complement each other well, as they are both designed to handle highly intensive and asymmetric functions in a cost effective manner with minor technical risks and smooth migration paths," said Kaivan Karimi, senior strategic marketing manager for Motorola's RF and DSP Infrastructure Division. "The TD-SCDMA libraries we're announcing are designed to enhance RCF by providing a cost-effective, standards-based solution with low power and ASIC-like deterministic performance."

The TD-SCDMA libraries are designed to enhance the MRC6011 RCF device's ability to perform the heavily matrix-oriented operations that power uplink and downlink chip rate algorithms in TD-SCDMA. With these libraries, the same array can be reconfigured to perform the sequence of matrix operations required for uplink joint detection or downlink beamforming. In addition, the flexibility and the processing power of the MRC6011 allow future algorithm enhancements without having to change hardware, enabling speedy time to market and smooth and low-risk migration for 3G and emerging 4G standards.

Joint detection, the process of canceling interference so that the data rates can push closer to theoretical radio-signal support limits, is one of the crucial features of TD-SCDMA that enables the standard to deliver increased capacity for the mobile Internet. With the addition of Motorola's TD-SCDMA libraries for the MRC6011, a developer can use the same piece of silicon to perform multiple simultaneous algorithmic operations needed for joint detection. Beyond joint detection, the ability of the TD-SCDMA libraries to perform high-speed matrix operations complements the processing array architecture of the MRC6011. Key high-speed matrix operations include matrix-vector product, matrix multiplication, Hermitian matrix linear solve, Hermitian matrix inverse, and Fast Fourier Transform/Inverse Fast Fourier Transform (FFT/IFFT).
