Outage probability guaranteed relay selection in cooperative communications

This study is focused on the multiple relay selection problem in cooperative communications. The objective is to select the minimum set of relays to minimise the spectrum cost while preserving the signal-to-noise ratio (SNR) requirement at the destination. A probabilistic constraint is adopted to ch...
