Compressive cooperative schemes with multiple relays

This paper studies multi-relay compressive cooperative schemes in which the source and the relays utilize compressive sensing (CS) as joint source-channel coding (JSCC). We consider four decode-and-forward (DF) strategies to forward the CS measurements here, namely receive diversity, code diversity, successive decoding and concatenated decoding, and derive their respective achievable rates in the following two cases. 1) The achievable rates of the schemes in which all the relays help to transmit the source message are derived under a overall power constraint. 2) Compressive cooperative schemes with relay selection are studied, where only the best relay is used to forward the signals. Simulation results demonstrate that our schemes use multiple relays effectively, for they have larger capacity than the single relay schemes, and it depends on the channel conditions that which scheme of the four performs best.
