In this paper, the performance of multiple-input multiple-output (MIMO) dual-hop amplify-and-forward (AF) relay systems using orthogonal space-time block codes (OSTBCs) over arbitrarily correlated Nakagami- m fading channels is analyzed. In particular, closed-form expressions for the end-to-end outage probability (OP) and the symbol error probability (SEP) with arbitrary number of transceiver antennas...
In this paper, we analyze the performance of dual-hop channel state information (CSI)-assisted amplify-and-forward (AF) cooperative networks using orthogonal space-time block codes (OSTBCs) over independent but not identically distributed Nakagami-m fading channels. Specifically, we present closed-form expressions of the outage probability (OP) and the symbol error probability (SEP). The analytical...
Multiple Antenna (MA) systems are fundamental in wireless communications. MA systems provide two kinds of advantages, namely diversity gain and multiplexing gain. However, there is an inherent tradeoff between the two, under slow fading conditions and is captured in [1] under asymptotically high signal to noise ratio (SNR). This is known as the Diversity Multiplexing Tradeoff (DMT). It has emerged...
