Decision-Feedback Aided Multiple-Symbol Differential Detection in Two-Way Relay Transmission

Decision-Feedback Aided Multiple-Symbol Differential Detection in Two-Way Relay Transmission

In this paper, noncoherent transmission algorithms are proposed in a two-way relay transmission (TWRT), where differential space-time block codes based multiple-symbol differential detection (MSDD) is performed. Specifically, generalized likelihood ratio test aided MSDD (GLRT-MSDD) is developed with...
