RF imperfections in high-rate wireless systems: impact and digital compensation

Wireless communication systems are persistently applying wider bandwidths, larger signal dynamics and higher carrier frequencies to fulfil the demand for higher data rates. This results in an ever increasing demand on the performanceof low-cost and power-efficient radio frequency (RF) front-ends. Since the RFtechnology is, consequently, pushed to its operation boundaries, the intrinsic imperfections of the RF IC technology are more and more governing the systemperformance of wireless modems. RF Imperfections in High-rate Wireless Systems therefore presents a new vision on the design of wireless communication systems. In this approach the imperfections of the RF front-ends are accepted and digital signal processing algorithms are designed to suppress their impact on system performance. To illustrate this approach, the book focuses on multiple-antenna orthogonal frequency division multiplexing (MIMO OFDM), which will be applied as basis for the majority of near-future high-rate wireless systems. Presents a contemporary multidisciplinary view on wireless systems design Combines mathematical derivations with intuitive explanations to provide the readerwith insights in RF imperfections One of the first books appearing on the emerging research topic of digital compensation of RF imperfections Combines sensitivity analyses with the design of compensation algorithms INDICE: From the contents Foreword.
