摘要：

Motivated by the recent development of spatial modulation (SM) and differential space-time shift keying (DSTSK), we propose a reduced-complexity conventional differential detector (CDD) as well as its reduced-complexity multiple-symbol differential sphere detector (MSDSD) counterpart for DSTSK. Both schemes operate on a symbol-by-symbol basis in order to reduce the complexity of the classic block-by-block-based CDD and MSDSD, whilst still attaining the optimum performance of the full-search-based ML detector.
