Abstract

This paper presents a 4×4/8×8/12×12 and QPSK/16-QAM/64-QAM reconfigurable MIMO detector on a multi-core DSP platform for different MIMO detection algorithms, including multiple-candidate-selection QRSIC (MCS-QRSIC), distributed K-best, and sorting-reduced K-best detectors. This study uses an Eigen-value decomposition method to investigate the intrinsic degree of parallelism of MIMO detectors and allocate the processing elements to DSP cores. MCS-QRSIC outperforms other detectors in 4 × 4 detection, and distributed K-best has the best performance in 8×8 and 12×12 MIMO systems. The normalized throughput achieves 188/153/142 Mbps for 64-QAM 4×4/8×8/12×12 MIMO detections at a 1GHz clock rate with 448 cores.
