The book "RF Imperfections in High-rate Wireless Systems" offers a modern, interdisciplinary perspective on radio systems. It examines the advantages of digital signal processing to meet the increasing demands for more powerful and flexible high-frequency circuits. Instead of focusing solely on the perfection of analog circuits, this work acknowledges the imperfections of these circuits and presents methods for mitigating and compensating for these imperfections. This leads to significant improvements in the overall solution compared to traditional approaches. The book highlights the evolution of wireless communication and the associated challenges that have changed over the years. In particular, it addresses the slow development of analog technology compared to digital processors, which are increasingly seen as a bottleneck for faster communication systems.
