摘要：

In view of the inaccuracy of the estimated symbols on the edge of the observation window, a decision-feedback subset aided multiple-symbol differential detection (MSDD) framework, dubbed DF-S-MSDD, is proposed in ultra-wideband impulse radio (UWB-IR) system with differential space-time block-code (DSTBC) modulation. Specifically, motivated by the decision-feedback aided MSDD (DF-MSDD), a subset of the decision-feedback symbols is selected, and the optimal symbols are preserved, and then all the remaining symbols are optimized. Furthermore, the simulations validate that the proposed DF-S-MSDD provides solid bit error-rate performance with a low complexity in UWB-IR system with DSTBC modulation.
