Joint Transmit Rate, Power and Antenna Allocation for MIMO Systems with Multimedia Traffic Kai ZHANG Zhisheng NIU Publication IEICE TRANSACTIONS on Communications Vol.E89-B No.6 pp.1939-1942 Publication Date: 2006/06/01 Online ISSN: 1745-1345 DOI: 10.1093/ietcom/e89-b.6.1939 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Wireless Communication Technologies Keyword: adaptive transmission, MIMO systems, multimedia traffic, Full Text: PDF(245.5KB)>>
Summary: This paper proposes an adaptive transmission scheme for MIMO systems to provide different bit error rates and transmission rates for multimedia traffic. The adaptive transmission scheme allocates antennas, rate and power jointly according to the feedback information to satisfy the diverse QoS requirements of the multimedia traffic. Furthermore, an efficient search algorithm with low complexity is proposed for practical implementation. Simulation results show that the proposed scheme improves the spectral efficiency while guaranteeing the QoS requirements of multimedia traffic. Moreover, the proposed search algorithm achieves close optimal performance with great complexity reduction. | |||||
