Xilinx Smarter Radio Solutions Address Performance Needs of Next-Generation LTE and MultiCarrier-GSM Platforms

Crest Factor Reduction and Digital Pre-Distortion SmartCORE IP enable wireless radio efficiency up to 50 percent, resulting in OpEx savings

SAN JOSE, CA -- Xilinx, Inc. announced availability of its Smarter Radio Solutions that meet the performance, power and cost needs of next-generation LTE and Multi-Carrier GSM (MC-GSM) platforms. These new solutions include Crest Factor Reduction (CFR) and Digital Pre-Distortion (DPD), part of the Xilinx® SmartCORE™ IP suite, to enable radio efficiency up to 50 percent, resulting in savings of tens of millions of dollars in OpEx for network operators. The combination of high efficiency provided by Xilinx CFR and DPD SmartCORE IP, and the Zynq®-7000 All Programmable SoC allows a single chip radio implementation, reducing board space, decreasing overall power, and simultaneously lowering total cost.

As the demand for data is constantly increasing, the average revenue per user (ARPU) is not increasing at the same rate, causing operators to explore new frequency bands, increased radio spectrum, and new network architectures. Operators must improve the efficiencies of their networks, while simultaneously managing energy costs. The enhanced Xilinx CFR and DPD IP cores allow for higher levels of power efficiency. Greater than 40 percent efficiency can easily be achieved for LDMOS based Power Ampliers and up to 50 percent for GaN based Power Amplifiers. Xilinx CFR and DPD IP supports a wide radio spectrum – up to 100Mhz – addressing the TD-LTE and FD-LTE standards, while also supporting multi-standard implementations requiring legacy support for MC-GSM. The DPD and CFR solutions are scalable to support:

• Multiple air interfaces standards (LTE (TDD/FDD), MC-GSM, WCDMA, CDMA2000, TD-SCDMA)
• Multiple antennas
• Higher correction performance
• Faster convergence time
• Multi-RAT configurations ((WCDMA + GSM, LTE + GSM on the same radio)

"Xilinx's highly scalable CFR and DPD IP enabled us to rapidly develop and integrate the digital system elements of a high performance, commercial LTE system," said Jaewon Kim, president of KMW Communications. "The Xilinx radio IP is extremely efficient, running at high clock rates in the 28nm Zynq SoC devices and allows our Radio Remote Head and Active Antenna to satisfy our customer requirements with maximum integration and greater flexibility than would be feasible with ASSP and ASICs."

"Xilinx's software and hardware programmable single device radio solutions allow the same board to be used for multiple configurations, significantly reducing development time and risk for customers developing smarter wireless solutions," said David Hawke, director, wireless product marketing for Xilinx. "This platform approach future-proofs deployments and offers the ability to respond quickly to changing requirements."
