Relay Selection Based Full-Duplex Cooperative Systems Under Adaptive Transmission
This letter analyzes multi-relay full-duplex systems with relay selection under multipath fading conditions in the context of channel capacity under: 1) optimum power and rate adaptation and 2) truncated channel inversion with fixed rate. Useful analytic expressions are derived for these measures as...

| description | This letter analyzes multi-relay full-duplex systems with relay selection under multipath fading conditions in the context of channel capacity under: 1) optimum power and rate adaptation and 2) truncated channel inversion with fixed rate. Useful analytic expressions are derived for these measures as well as for the associated optimum cut-off level. The offered results are then employed in the analysis of the corresponding end-to-end performance by also quantifying the effects of the involved relay self-interference. It is shown that high capacity levels are achieved even for a moderate number of relays and self-interference levels, at no considerably added system complexity. This is particularly useful in demanding emerging applications that are subject to transmit power constraints or fixed rate requirements. |
