Abstract

Past few years witnessed a tremendous growth in the demand for wireless services and huge increase in the number of mobile subscribers. Recent CISCO forecasts reveal that Global mobile data traffic grows 74 percent in 2015, where it reached 3.7 Exabytes per month at the end of 2015 comparing to 2.1 Exabytes per month at the end of 2014. Also and in the same forecasts, it is reported that mobile data traffic has grown 4,000-fold over the past 10 years and almost 400-million-fold over the past 15 years. As such, mobile operators and researchers are trying their best to develop new transmission technologies, protocols and network infrastructure solutions to enhance the achievable throughput and the overall spectral efficiency. A promising solution to achieve the targeted data rate is anticipated through multiple-input multiple-output (MIMO) technology deployment. Spectrum scarcity is the main factor that limits the vision for high speed wireless access. Overcoming this challenge requires innovative ways for spectrum sensing and reuse. MIMO technology promises a linear gain in capacity with the number of antennas. Unfortunately, this linear gain requires high complexity transceivers and suffers from practical imperfections such as, spatial correlation, mutual coupling and others. Space modulation techniques, such as spatial modulation (SM), space shift keying (SSK) and quadrature spatial modulation (QSM), are proposed to alleviate most of these precincts. In such techniques, specific transmit antenna or antennas is activated and the index of the active antenna conveys extra modulation bits to achieve spatial multiplexing gain. Likewise, simple transceiver architecture can be considered and these techniques are shown to be robust to several imperfections as compared to other MIMO techniques. As such, it attracted momentous research interest in the past few years. This tutorial provides a comprehensive overview of these techniques, the basic working principle, and the differences among them. The advantages and disadvantages of each technique along with their detailed performance will be discussed. A general framework for analyzing the performance of these techniques over generalized fading channels will be given.
