Baudin P. Wireless transceiver architecture. Bridging RF and digital communications

754 pp. 2015 John Wiley & Sons, Ltd
This book consists of three parts. Part I focuses on the explanation of what is expected from a transceiver. This part is composed of three chapters dedicated to the three areas that drive those requirements: (a) the digital communications theory itself, which allows us to define the minimum set of signal processing functions to be embedded in a transceiver, as well as introducing key concepts such as complex envelopes; (b) the electromagnetism theory, as theoretical results in the field of propagation allow us to explain some architectural constraints for transceivers; (c) the practical organization of wireless networks, as it drives most of the performance required from transceivers in practice. By the end of Part I we should thus have an understanding of the functionalities required in a transceiver as well as their Part II is then dedicated to a review of the limitations we face in the physical implementation using electronic devices of the signal processing functions derived in Part I. Those limitations are sorted into three groups, leading to three chapters dedicated to: (a) the noise sources to be considered in a line-up; (b) the nonlinearity in RF/analog components; (c) what are classically labeled RF impairments. Part III then turns to the transceiver architecture and system design itself. We can now focus on how to dimension a transceiver that fulfills the requirements derived in Part I while taking into account the implementation limitations reviewed in Part II. Practically speaking, this is done through three chapters. The first of these is dedicated to the illustration of a transceiver budget for a given architecture. This shows how a practical line-up budget can be done, i.e. how the constraints linked to the implementation limitations can be balanced between the various blocks of a given line-up in order to achieve the performance. The second chapter reviews different architectures of transceivers. In contrast to what is done in the previous chapter, we can see here how the fundamental limitations of a given line-up can be overcome by changing its architecture. The third chapter then examines some algorithms classically used for improving or optimizing the performance of transceiver line-ups.
