This book is a synthesis of the tasks and research experiences carried out in the Laboratory of Signal Processing and Communications (LaPSyC), CONICET, Universidad Nacional del Sur, Argentine, since 2003.It includes broadly known models and techniques, used in the signal processing community, which facilitates their application and understanding.Emphasis is placed on methodologies of low complexity and scalable to different applications. It also emphasizes measures of performance and impact of each compensation technique in the corresponding context.To allow a more direct reading, not only for academic community but also for industry, the contents are divided into three parts: 1) basic models 2) compensation techniques and 3) applications inadvanced technologies.The first part describes, on the one hand, basic architectures of transceivers and their component blocks, and on the other, modulation techniques. Together they describe the behavior to be taken into account, regardless of the distortions to compensate produced by the specific technologies of implementation.In the second part, several schemes of compensation and / or reduction of imperfections are addressed, among which we highlight: linearization of power amplifiers, compensation of the characteristic of analog digital converters and CFO compensation for OFDM modulation.In the third part, some of the previous techniques are used in modern applications of wireless communications systems such as: full-duplex transmission, massive MIMO schemes and finally applications in internet of things.
