In this paper, we present space shift keying (SSK) as a new modulation scheme, which is based on spatial modulation (SM) concepts. Fading is exploited for multiple-input multipleoutput (MIMO) channels to provide better performance over conventional amplitude/phase modulation (APM) techniques. In SSK, it is the antenna index used during transmission that(More)
In this letter, we derive the optimal detector for the so-called spatial modulation (SM) system introduced by Mesleh et al. in [1]. The new detector performs significantly better than the original (~4 dB gain), and we support our results by deriving a closed form expression for the average bit error probability. As well, we show that SM with the optimal(More)
A fundamental component of spatial modulation (SM), termed generalized space shift keying (GSSK), is presented. GSSK modulation inherently exploits fading in wireless communication to provide better performance over conventional amplitude/phase modulation (APM) techniques. In GSSK, only the antenna indices, and not the symbols themselves (as in the case of(More)
A new technique for color image enhancement in the compressed domain is presented here. The proposed technique is simple and more effective the existing techniques reported earlier. The important feature of proposed technique is that it treats the chromatic components, while previous techniques treated only the luminance component. The proposed algorithm(More)
Spatial modulation (SM) is a recently developed transmission technique that uses multiple antennas. The concept of SM is extended to both the space and time dimensions to provide a general shift-keying framework. A new modulation scheme called Differential STSK (DSTSK) scheme, assisted by the Cayley unitary transform is proposed to OFDM aided Multiple Input(More)
