Differential Space–Time Shift Keying-Aided Successive-Relaying-Assisted Decode-and-Forward Cooperative Multiuser CDMA
"... Abstract—A differential space–time shift keying (DSTSK)-aided successive-relaying-assisted multiuser decode-and-forward (DF) cooperative system is proposed. We employ low-complexity noncoherent detection, which requires channel state information (CSI) at neither the relay nodes (RNs) nor at the dest ..."

at the destination node (DN). More explicitly, the source nodes (SNs) employ differen-tially encoded phase-shift keying (PSK) modulation, whereas the RNs perform soft-input–soft-output multiple-symbol differential sphere decoding (SISO-MSDSD)-based DF relaying during the relaying phase. Similarly, DSTSK transmission

Soft-Input Soft-Output Lattice Sphere Decoder for Linear Channels
- Proc. of the IEEE GLOBECOM’03
, 2003
"... Soft output detection for signals transmitted on linear channels is investigated. A particular emphasis is made for signal detection on multiple antenna channels. The a posteriori information at the detector output is evaluated from a shifted spherical list of point candidates. The spherical list is ..."

Thus, the sphere radius is selected in order to control the list size and to cope with the boundaries of the finite multiple antenna constellation. Our new soft output sphere decoder is then applied

On the Improved Path Metric for Soft-input Soft-output Tree Detection
"... Abstract—In this paper, we propose a new path metric, which improves the performance of soft-input soft-output (SISO) tree detection for iterative detection and decoding (IDD) systems. While the conventional path metric accounts for the contribution of symbols on a visited path due to the causal nat ..."
