Abstract: In this paper, we propose a simple yet powerful mapping scheme that converts any conventional square-matrix-based differential space-time coding (DSTC) into a nonsquare-matrix-based DSTC. This allows DSTC schemes to be used practically in open-loop large-scale… read more here.

Abstract: We propose a new single-RF differential space–time block coding using index shift keying (DSTBC-ISK), which is the first differential space–time modulation (DSTM) scheme that can simultaneously achieve the following three imperative objectives: First, forming a… read more here.

Abstract: Differential spatial modulation (DSM) is a multi-antenna technique that does not require channel state information (CSI). However, DSM has a deficiency of low spectral efficiency (SE). In this paper, a differential space-time media-based modulation (DSTMBM)… read more here.

DOI: 10.1109/twc.2022.3208079
Abstract: This article proposes two low complexity decoders for non coherent differential space shift keying (DSSK) multiple input multiple output (MIMO) system by representing the detection problem as a hierarchical tree structure. Such presentation enables yielding… read more here.
