Title:	Diversity-Multiplexing Tradeoff of OSTBC Over Correlated Nakagami-m Fading Channels
Authors:	Jiee Chen, Xiqi Gao, Southeast University, China
Abstract:	This paper investigates the tradeoff between diversity and multiplexing of orthogonal space-time block coding (OSTBC) for correlated Nakagami-m fading. For a given transmission rate, the outage probability as function of the multiplexing gain and signal-to-noise ratio (SNR) is derived. Following the negative slope of the outage probability versus SNR curve, we obtain the diversity gain at finite SNR and its maximum attainable value to predict the system performance at operating SNR's. In addition, the asymptotic diversity gain at high SNR is given via two approaches, which provides a theoretical limit for practical SNR's. The impact of the complex component correlation among the channel links on the outage performance is also presented.
