Performance Analysis of Randomized Distributed Space-Time Codes over Composite Gamma/Lognormal Fading Channels
This work investigates the end-to-end performance of randomized distributed
space-time codes with complex Gaussian distribution, when employed in a
wireless relay network. The relaying nodes are assumed to adopt a
decode-and-forward strategy and transmissions are affected by small and large
scale fading phenomena. Extremely tight, analytical approximations of the
end-to-end symbol error probability and of the end-to-end outage probability
are derived and successfully validated through Monte-Carlo simulation. For the
high signal-to-noise ratio regime, a simple, closed-form expression for the
symbol error probability is further provided
