TurboConcept has ported and tested its TC1000-WiMAX, an 802.16 Convolutional Turbo Code decoder IP core, on Lattice's FPGA devices.

The core supports all modes of the IEEE 802.16 CTC standard, including Orthogonal Frequency Division Multiplexing (OFDM) PHY and Orthogonal Frequency Division Multiple Access (OFDMA) PHY.

As part of the deal, TurboConcept becomes a member of Lattice's ispLeverCORE Connection program, and the companies will provide complete systems to designers integrating system-level IP with Lattice's FPGA architectures.

"Broadband wireless access is poised for exceptional growth, and FPGAs are a great fit for this growing market because their reprogrammability enables the instant design changes necessary to keep pace with evolving standards," said Stan Kopec, Lattice corporate VP of marketing. "To deliver maximum value, the FPGAs also must perform CTC decoding, which is why we are excited to join with our new IP partner, TurboConcept, as we continue our expansion into broadband wireless access."

TurboConcept is a pioneer in Turbocode IP. Turbocodes were invented by Claude Berrou and Alain Glavieux at ENST-Bretagne in 1993. They have been adopted in CCSDS, UMTS, DVB and IEEE international standardization committees and the company, founded in 1999, says they typically outperform concatenated Viterbi and Reed-Solomon codes by 2 dB or more.

"In a WiMAX system, the CTC decoder is one of the most demanding functions in terms of computational complexity, which makes it desirable to implement the decoder in an FPGA," said Jacky Tousch, TurboConcept's co-founder and CTO.
