Extended spatial modulation (ESM) is proposed as a novel spatial modulation scheme in this paper. Extended spatial modulation is a spatial modulation design where the number of active antennas can be various. The data rate could be improved as more symbols are available for transmitting and thus more information bits can be modulated during each time slot. The minimum distance of the transmitted symbols...
In this paper, an extended space shift keying (ESSK) modulation scheme for MIMO channels is proposed to improve the symbol error probability (SEP) and spectral efficiency of traditional generalized space shift keying (GSSK). Compared to traditional GSSK, the number of active antennas of each time slot in ESSK can be different from symbol to symbol, which improves the spectral efficiency significantly...
In this letter, a novel signal vector based detection (SVD) scheme for spatial modulation (SM) system is proposed. For analytical tractability, we focus on the system in which only one antenna is active during one time slot. Through the theoretical analysis and simulation results, it is shown that the performance of SVD scheme can agree well with the result of the optimal maximum likelihood (ML) detection...
