8.1 Summary

Space modulation techniques (SMTs) were presented, analyzed, and thoroughly discussed in this book. The book presented a comprehensive overview of different SMTs and analyzes their performance. SMTs are new and unique multiple‐input multiple‐output (MIMO) wireless communication systems. Most of the existing analysis in literature cannot be directly applied to SMTs. It is shown in this book that SMTs need different system designs for both transmitter and receiver. Also, the performance analysis for these systems requires different studies, which go beyond existing theory. In SMTs, new constellation diagram is defined and used to convey information. In previous theory of MIMO systems, multipath propagation channel is used to increase the channel capacity of wireless systems. Uncorrelated channel paths from different transmit antennas are utilized to transmit independent and cochannel data streams to increase the data rate. Such schemes generally achieve spatial multiplexing gain and they are called spatial multiplexing (SMX) MIMO systems. SMX systems suffer from inter‐channel interference (ICI), which degrades their error performance and complicates the receiver design. Also, each transmit antenna must be driven by a complete radio frequency (RF) chain including IQ modulators, filters, power amplifier (PA), and others. These components are generally very expensive and produce good amount of heat, which require proper cooling. Also, ...
