  Interest in selection relaying is growing. The recent developments in this
area have largely focused on information theoretic analyses such as outage
performance. Some of these analyses are accurate only at high SNR regimes. In
this paper error rate analyses that are sufficiently accurate over a wide range
of SNR regimes are provided. The motivations for this work are that practical
systems operate at far lower SNR values than those supported by the high SNR
analysis. To enable designers to make informed decisions regarding network
design and deployment, it is imperative that system performance is evaluated
with a reasonable degree of accuracy over practical SNR regimes. Simulations
have been used to corroborate the analytical results, as close agreement
between the two is observed.
