Differential space-time shift-keying aided successive-relaying-assisted decode-and-forward cooperative multiuser CDMA
A Differential Space-Time Shift Keying (DSTSK) aided and successive relaying assisted multi-user Decode-and-Forward (DF) cooperative system is proposed. We employ low-complexity non-coherent detection, which does not require any channel state information, neither at the Relay Nodes (RNs) nor at the Destination Node (DN). More explicitly, the source nodes employ differentially encoded phase-shift-keying modulation, while the RNs perform Soft-Input Soft-Output Multiple-Symbol Differential Sphere Decoding (SISO-MSDSD) based DF relaying during the relaying phase. Similarly, DSTSK transmission is employed at the RNs, which is detected with the aid of SISO-MSDSD at the DN. More explicitly, three-stage serial-concatenated turbo encoding/decoding is employed throughout the system in order to enhance the attainable performance. Additionally, a maximum minimum-determinant based configuration selection algorithm is proposed to select the optimal DSTSK configuration for supporting a specific number of users. Moreover, we adopt a successive relaying architecture for recovering the conventional 50% half-duplex relaying induced throughput loss, at the cost of supporting less users.

Abstract
A Differential Space-Time Shift Keying (DSTSK) aided and successive relaying assisted multi-user Decode-and-Forward (DF) cooperative system is proposed. We employ low-complexity non-coherent detection, which does not require any channel state information, neither at the Relay Nodes (RNs) nor at the Destination Node (DN). More explicitly, the source nodes employ differentially encoded phase-shift-keying modulation, while the RNs perform Soft-Input Soft-Output Multiple-Symbol Differential Sphere Decoding (SISO-MSDSD) based DF relaying during the relaying phase. Similarly, DSTSK transmission is employed at the RNs, which is detected with the aid of SISO-MSDSD at the DN. More explicitly, three-stage serial-concatenated turbo encoding/decoding is employed throughout the system in order to enhance the attainable performance. Additionally, a maximum minimum-determinant based configuration selection algorithm is proposed to select the optimal DSTSK configuration for supporting a specific number of users. Moreover, we adopt a successive relaying architecture for recovering the conventional 50% half-duplex relaying induced throughput loss, at the cost of supporting less users.
