The computationally intensive task of calculating the precoding and decoding matrices has been implemented and the underlying algorithm has been optimized for real-time capability, efficiency and flexibility. The required number of iterations has been optimized and appropriate low-latency algorithms for the computation of basic operations have been identified to meet a real-time constraint of 1ms processing latency. The architecture has been verified and synthesized for a Xilinx Virtex-6 LX550T FPGA. The maximum number of antennas, users and data streams is configurable at synthesis time. The actual parameters are configurable at runtime. Different degrees of parallelism allow a trade-off between resource requirements, latency and throughput. The target FPGA resources are sufficient for real-time system configurations up to 5 users with 3 antennas.
