Motivated by the recent concept of Spatial Modulation (SM), we propose a novel Distributed Space-Time Shift Keying (D–STSK) scheme, where the SM concept is extended to include both the space and time dimensions for the sake of achieving a flexible tradeoff between the multiplexing and diversity gains, in the context of cooperative space-time transmissions. More specifically, in our D–STSK scheme each Relay Node (RN) activates Decode-and-Forward (DF) transmissions, depending on the success or failure of Cyclic Redundancy Checking (CRC). We propose a novel bit-to D–STSK mapping rule, where according to the input bits, one of the Q pre-assigned dispersion vectors is activated to implicitly convey log2 Q bits, which are transmitted in combination with the classic log2 L-bit modulated symbol. Additionally, we introduce a beneficial dispersion vector design, which enables us to dispense with symbol-level Inter-Relay Synchronization (IRS). Furthermore, the Destination Node (DN) is capable of jointly detecting the signals received from the source-destination and relay-destination links, using a low-complexity single-stream-based Maximum Likelihood (ML) detector, which is an explicit benefit of our Inter-Element Interference (IEI)-free system model. More importantly, as a benefit of its design flexibility, our D–STSK arrangement enables us to adapt the number of the RNs, the transmission rate as well as the achievable diversity order.

Abstract

Motivated by the recent concept of Spatial Modulation (SM), we propose a novel Distributed Space-Time Shift Keying (D–STSK) scheme, where the SM concept is extended to include both the space and time dimensions for the sake of achieving a flexible tradeoff between the multiplexing and diversity gains, in the context of cooperative space-time transmissions. More specifically, in our D–STSK scheme each Relay Node (RN) activates Decode-and-Forward (DF) transmissions, depending on the success or failure of Cyclic Redundancy Checking (CRC). We propose a novel bit-to D–STSK mapping rule, where according to the input bits, one of the Q pre-assigned dispersion vectors is activated to implicitly convey log2 Q bits, which are transmitted in combination with the classic log2 L-bit modulated symbol. Additionally, we introduce a beneficial dispersion vector design, which enables us to dispense with symbol-level Inter-Relay Synchronization (IRS). Furthermore, the Destination Node (DN) is capable of jointly detecting the signals received from the source-destination and relay-destination links, using a low-complexity single-stream-based Maximum Likelihood (ML) detector, which is an explicit benefit of our Inter-Element Interference (IEI)-free system model. More importantly, as a benefit of its design flexibility, our D–STSK arrangement enables us to adapt the number of the RNs, the transmission rate as well as the achievable diversity order.
