Complexity Reduced Maximum Likelihood Detection for SDM-OFDM System Yuanrun TENG Katsuhiro NAITO Kazuo MORI Hideo KOBAYASHI Publication IEICE TRANSACTIONS on Communications Vol.E89-B No.7 pp.2084-2087 Publication Date: 2006/07/01 Online ISSN: 1745-1345 DOI: 10.1093/ietcom/e89-b.7.2084 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Wireless Communication Technologies Keyword: MIMO, SDM-OFDM, spatial diversity, MLD, Full Text: PDF(140.9KB)>>
Summary: This paper proposes two complexity reduced Maximum Likelihood Detection (MLD) methods for Space Division Multiplexing--OFDM (SDM-OFDM) system to exploit the spatial diversity so as to achieve the improved transmission quality. The proposed methods enable to outperform the other suboptimal detection methods and achieve near MLD performance with a significant reduction in calculation complexity. The various computer simulation results confirm that the proposed methods could realize the above targets and might be promising solution in practical systems. | |||||
