The desire to build lower cost analog front-ends has triggeredinterest in a new domain of research. Consequently the joint designof the analog front-end and of the digital baseband algorithms hasbecome an important field of research. It enables the wirelesssystems and chip designers to more effectively trade thecommunication performance with the production cost.
Digital Compensation for Analog Front-Ends provides asystematic approach to designing a digital communication system. Itcovers in detail the digital compensation of many non-idealities,for a wide class of emerging broadband standards and with a systemapproach in the design of the receiver algorithms. In particular,system strategies for joint estimation of synchronization andfront-end non-ideality parameters are emphasized. The book isorganized to allow the reader to gradually absorb the importantinformation and vast quantity of material on this subject. Thefirst chapter is a comprehensive introduction to the emergingwireless standards which is followed by a detailed description ofthe front-end non-idealities in chapter two. Chapter three thenuses this information to explore what happens when the topicsintroduced in the first two chapters are merged. The book concludeswith two chapters providing an in-depth coverage of the estimationand compensation algorithms.
This book is a valuable reference for wireless system architectsand chip designers as well as engineers or managers in systemdesign and development. It will also be of interest to researchersin industry and academia, graduate students and wireless networkoperators.
* Presents a global, systematic approach to the joint design ofthe analog front-end compensation, channel estimation,synchronization and of the digital baseband algorithms
* Describes in depth the main front-end non-idealities such asphase noise, IQ imbalance, non-linearity, clipping, quantization,carrier frequency offset, sampling clock offset and their impact onthe modulation
* Explains how the non-idealities introduced by the analogfront-end elements can be compensated digitally
* Methodologies are applied to the emerging Wireless Local AreaNetwork and outdoor Cellular communication systems, hence coveringOFDM(A), SC-FDE and MIMO
* Written by authors with in-depth expertise developed inthe wireless research group of IMEC and projects covering the mainbroadband wireless standards
