Xilinx Korea (Branch Manager An Heung-sik) February 20, 2014 – Xilinx announced the availability of smarter wireless solutions that meet the performance, power output, and cost requirements of next-generation LTE and multicarrier GSM (MC-GSM) platforms. The new solution, which includes Crest Factor Reduction (CFR) and Digital Pre-Distortion (DPD) as part of the Xilinx® SmartCORE™ IP product family, improves wireless efficiency by up to 50%, reducing tens of millions of dollars in operational costs required for network operations. Through the combination of high efficiency provided by Xilinx CFR and SmartCORE IP and the Zynq®-7000 all programmable SoC, single-chip wireless can be implemented, thereby reducing board space and overall power consumption to achieve lower total cost.

As data demand continues to grow but average revenue per user (ARPU) does not increase at the same rate, operators are seeking new frequency bands, increased wireless spectrum, and new network architectures. Operators face the challenge of managing energy costs while improving efficiency of their networks. Xilinx's enhanced CFR and DPD IP cores provide higher levels of power efficiency. Efficiency of over 40% can be achieved in LDMOS-based power amplifiers and up to 50% in GaN-based power amplifiers. Xilinx's CFR and DPD IP supports a broad wireless spectrum up to 100MHz compliant with TD-LTE and FD-LTE standards and supports multi-standard implementation requiring legacy support for MC-GSM. The DPD and CFR solutions are scalable to support the following:

• Multiple air interface standards (LTE (TDD/FDD), MC-GSM, WCDMA, CDMA2000, TD-SCDMA)
• Multiple antennas
• High calibration performance
• Fast conversion time
• Multiple RAT configurations (WCDMA + GSM, LTE + GSM on the same radio)

Kim Jae-won, CEO of KMW Communications, stated, "Through Xilinx's highly scalable CFR and DPD IP, we were able to rapidly develop and integrate digital system elements for high-performance commercial LTE systems." He added, "Xilinx wireless IP is highly efficient. Operating at high clock speeds in 28-nanometer Zynq SoC devices, it provides customers with significantly superior integration and flexibility through wireless remote heads and active antennas compared to ASSP and ASIC solutions."

David Hawke, Wireless Product Marketing Director at Xilinx, stated, "Using Xilinx's software and hardware programmable single-device wireless solution allows the same board to be used in various configurations, significantly mitigating development time and risk." He added, "This platform approach ensures competitive deployment in the future and provides the ability to rapidly respond to changing requirements."
