Cooperation Multiplexing： Research on Realizing Higher Spectrum Efficiency in Multi-antenna Relay Network
摘要
Abstract
Previous work on benefits of such techniques. cooperative communications has concentrated primarily on the diversity This paper, instead, considers the multiplexing benefits of cooperative communications. First, a new interpretation on the fundamental tradeoff between the transmission rate and outage probability in multiple-antenna relay networks is given. It follows that multiplexing gains can be obtained at any finite signal-to-noise ratio （SNR）, in full-duplex multiple-antenna relay net- works. Thus, relaying can offer not only stronger link reliability, but also higher spectral efficiency. It is shown that this power gain can significantly affect the system diversity-multiplexing tradeoff for any finite SNR value.关键词
