Abstract

The concepts of cooperative diversity promise to offer the benefits of spatial diversity gains to handheld wireless devices with single antennas. So far the research has focused on the situation where perfect channel state information is available and coherent detection is employed at the destination receiver. This paper proposes a differential super-orthogonal space-time trellis code modulation scheme for a two-user cooperative diversity system, which does not require channel state information at either users or destination while providing a performance about 1. 5 dB better than DSTBC and 3 dB worse than the corresponding coherent scheme.
