mm-wave 256-QAM modem implemented as IP in FPGA

February 19, 2014 // By Graham Prophet
Xilinx has announced a 1.6 Gbps low power, low cost, small cell backhaul modem, in the form of SmartCORE IP for millimetre wave applications; the 256 QAM modem supports both point to point as well as point to multipoint line-of-sight communications, addressing both 60-GHz and 80-GHz markets

Added to Xilinx’ SmartCORE IP portfolio, this solution consumes less than 5W at data rates of over 1 Gbps. Customers note that its TDD multiplexing support is an additional feature which allows this IP to scale well from small footprint, low power, to high throughput wideband configurations.

“[in the LTE market] we are in a period of unprecedented data growth, where wireless backhaul has a prominent role” said Tarmo Pihl, wireless marketing director for Xilinx. “The 256 QAM millimeter wave modem IP will scale from 1+Gbps data rates today, to 10 Gbps in the future, and is designed to support the major shift and growth in mobile broadband traffic.”

The highly configurable point-to-point and point-to-multipoint millimeter wave modem IP core incorporates all the key features and capabilities to accelerate development of next-generation wireless solutions. suitable for outdoor deployment, the modem IP offers a highly scalable solution from low power small cell backhaul to high throughput wireless front haul applications using a common platform. It also supports several IP configurations such as a modem with either RS FEC or LDPC FEC, CPRI for fronthaul or 10GbE interface for backhaul, and JESD204B for a new generation of converter devices. The modem supports hitless and errorless adaptive modulation, analogue imperfection compensation, TDD and FDD multiplexing technologies with higher layer protocol interface, and granular channel bandwidths. The low DSP latency makes it suitable for wireless fronthaul applications with very stringent latency requirements.
