Over the last few decades wireless communications, especially Mobile Communication Technology, has evolved by leaps and bounds. The mobile communication industry has named the different major changes as generations namely 1G, 2G,..5G. We are presently looking at deployment of 5G technologies. The work for 6G has already started. This book is focused on the waveform design of 6G. It presents a discourse on a potential waveform for 6G namely Orthogonal Time Frequency Space (OTFS) modulation. OTFS has a distinct feature when compared to earlier generation waveforms such that information bearing signal is placed in the delay Doppler domain as opposed to the usual placement of such signals in the time-frequency domain. This unique feature of OTFS enables it to overcome several disadvantages of a very popular and highly successful waveform namely Orthogonal Frequency Division Multiplexing (OFDM). OTFS is known to be more resilient to frequency offset and Doppler which is one of the key drawbacks of OFDM. With this feature, OTFS, can support higher mobility as well as higher frequency bands of operation which is also one of the key requirements of the next generation wireless communication technologies. The implementation complexity of OTFS remains comparable to that of OFDM. It is found that OTFS provides significant SNR advantage, higher resilience, lower PAPR, lower out of band signal leakage and higher multi-user spectral efficiency than that of OFDM. This book addresses• Fundamental signal model of OTFS. • Receiver design for OTFS• Channel estimation in OTFS• Multiple Access through non-orthogonal multiple access (NOMA-OTFS) The contents of the books are primarily outcome of the research work done at the G. S. Sanyal School of Telecommunications, Indian Institute of Technology Kharagpur, Kharagpur, India. Orthogonal Time Frequency Space Modulation : A waveform for 6G is ideal for personnel the wireless communication industry as well as academic staff and master/research students in electrical engineering with a specialization in wireless communications.

This monograph serves as a much-needed, self-contained reference on the topic of modulation spaces. By gathering together state-of-the-art developments and previously unexplored applications, readers will be motivated to make effective use of this topic in future research. Because modulation spaces have historically only received a cursory treatment, this book will fill a gap in time-frequency analysis literature, and offer readers a convenient and timely resource. Foundational concepts and definitions in functional, harmonic, and real analysis are reviewed in the first chapter, which is then followed by introducing modulation spaces. The focus then expands to the many valuable applications of modulation spaces, such as linear and multilinear pseudodifferential operators, and dispersive partial differential equations. Because it is almost entirely self-contained, these insights will be accessible to a wide audience of interested readers. Modulation Spaces will be an ideal reference for researchers in time-frequency analysis and nonlinear partial differential equations. It will also appeal to graduate students and seasoned researchers who seek an introduction to the time-frequency analysis of nonlinear dispersive partial differential equations.

Spatial modulation (SM) is a recently proposed modulation scheme for multi-antenna systems exploiting the space domain as well as the signal domain to modulate the information. In this scheme, an amplitude-phase modulation (APM) technique is combined with the space shift keying (SSK) to send the information over a multi-input multi-output (MIMO) channel. In the SSK, each data symbol is associated to one specific transmit antenna such that in each transmit interval, to transmit a particular symbol, only the corresponding transmit antenna is active. Several benefits of SSK and SM transmission and their advantages over traditional MIMO transmission schemes have been addressed in the literature. The low transmission/reception complexity of these transmission techniques makes them a suitable candidate for future wireless systems especially when the number of antennas at the transmitter is large. For example, SSK/SM can be considered as a technique applicable to massive MIMO communication to support high dimension modulations. Having many antennas at the transmitter enables modulating the information via space which can increase the rate significantly while only using one radio frequency (RF) chain at the transmitter to avoid complexity. The aim of this dissertation is to evaluate the error performance of SM systems and develop signal processing techniques to improve the performance of these systems. Several techniques including adaptive space modulation (ASM), antenna subset selection (ASS) and spatial modulation constellation design are studied and evaluated. For ASM, we propose a new approach to assign different powers and phases to different antennas based on the available channel state information at the transmitter (CSIT). We also introduce a very low-complexity search scheme to select a set of antennas among all available transmit antennas using CSIT. Simulation results show that both ASM and ASS improve the error performance of SM systems by providing a diversity gain. The constellation design for SM is also investigated in this dissertation. This includes the constellation balancing between space/APM domains and APM constellation design for specific SM structure. We also study a suboptimal detection called maximum ratio combining (MRC) to reduce the complexity compared to the optimal maximum likelihood (ML) detection and investigate ASM, ASS and SM constellation design for MRC-based SM systems. Finally, a new simple space modulation scheme for downlink transmission in a multi-user system is proposed and its error performance is evaluated.
