Throughput-reliability tradeoff in decode-and-forward cooperative relay channels: A network information theory approach

Abstract: Abstract-Cooperative transmission protocols are always designed to reach the largest diversity gain and the largest network capacity simultaneously. The concept of diversity-multiplexing tradeoff (DMT) in MIMO systems put forward by Zheng and Tse has been extended to this field. However, the concept of multiplexing gain in DMT constrains a better understanding of the asymptotic interplay between transmission rate, frame error probability (FEP) and signal-to-noise ratio (SNR), and also fails to predict FEP curv… Show more

“…Each of these inflexions split the DMT curve into segments, which corresponds to the operating region of TRT for general fading channels. Comparing the DMT of general fading channel in (12) and TRT of general fading channel equations in Theorem 1, we find that relation between DMT and TRT of MIMO with general fading channel conditions also satisfy (11), like MIMO and co-operative systems under Gaussian fading conditions [3,6,7]. Thus, any MIMO system under any fading scenario may have same relationship between DMT and TRT.…”
