Space Modulation Transmission and Reception Techniques

This chapter discusses different space modulation techniques (SMTs) available in the literature. These include space shift keying (SSK), generalized space shift keying (GSSK), spatial modulation (SM), generalized spatial modulation (GSM), quadrature space shift keying (QSSK), quadrature spatial modulation (QSM), generalized quadrature space shift keying (GQSSK) and generalized quadrature spatial modulation (GQSM). The advanced SMTs include differential space shift keying (DSSK), differential spatial modulation (DSM), differential quadrature spatial modulation (DQSM), space‐time shift keying (STSK), and trellis coded spatial modulation (TCSM) systems. One of the main advantages of SMTs is that they allow for simple receiver architecture with reduced complexity as compared to SMX and other multiple‐input multiple‐output (MIMO) systems. The chapter evaluates the approximate transmitter power consumption for different SMTs. A rough estimate of the implementation cost for each SMTs and generalized SMTs system is calculated based on the available off‐the‐shelf components. The chapter shows spectral efficiency of differential SMTs.
