| Resumo |
In this paper, a low-complexity soft-output QRD-M detection algorithm is proposed for high-throughput Multiple-input multiple-output (MIMO) systems. By employing novel expansion on demand and distributed sorting scheme, the proposed algorithm can reduce 70% and 85% foundational operations for 16-QAM and 64-QAM respectively compared to the conventional QRD-M algorithm. Furthermore, the proposed algorithm can yield soft information to improve the bit error rate (BER) performance. Simulation results show that the proposed algorithm can achieve a near-NIL detection performance with less foundational operations Submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-13T04:34:52Z No. of bitstreams: 1 A Simplified Soft-output QRD-M MIMO Detector.pdf: 280645 bytes, checksum: 0691f9838548ac0a588a375c0e566a31 (MD5) Made available in DSpace on 2010-04-13T04:34:52Z (GMT).
