Reconfigurable K-best MIMO detector architecture and FPGA implementation

In a MIMO communication system, K-best decoding algorithm achieves near optimal performance with reduced complexity. Simulation results show that a reconfigurable MIMO detector can improve system performance over a wide range of operating conditions. In this paper we present a low complexity reconfigurable architecture for implementation of K-best algorithm. Implementation results using FPGA technology demonstrate a throughput of 240Mbps
