Xilinx has LTE radio IP available

Xilinx has current availability of radio IP For LTE and Multi-Carrier GSM (MC-GSM) platforms which have Crest Factor Reduction (CFR) and Digital Pre-Distortion (DPD) features enabling radio efficiency up to 50 percent.
Xilinx CFR and DPD SmartCORE IP, and the Zynq-7000 programmable SoC allows a single chip radio implementation.

ARPU is not increasing at the same rate as data usage, causing operators to explore new frequency bands, increased radio spectrum, and new network architectures.

Xilinx claims the enhanced CFR and DPD IP cores allow for greater than 40% efficiency can easily be achieved for LDMOS based Power Ampliers and up to 50% for GaN based Power Amplifiers.

The CFR and DPD IP supports radio spectrum up to 100Mhz and addresses the TD-LTE and FD-LTE standards, while 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)
