Description of  FPGA-based Digital Convolution for Wireless Applications

This book presents essential perspectives on digital convolutions in wireless communications systems and illustrates their corresponding efficient real-time field-programmable gate array (FPGA) implementations. FPGAs or generic all programmable devices will soon become widespread, serving as the brains of all types of real-time smart signal processing systems, like smart networks, smart homes and smart cities. The book examines digital convolution by bringing together the following main elements: the fundamental theory behind the mathematical formulae together with corresponding physical phenomena virtualized algorithm simulation together with benchmark real-time FPGA implementations and detailed, state-of-the-art case studies on wireless applications, including popular linear convolution in digital front ends (DFEs) nonlinear convolution in digital pre-distortion (DPD) enabled high-efficiency wireless RF transceivers and fast linear convolution in massive multiple-input multiple-output (MIMO) systems. After reading this book, students and professionals will be able to: Understand digital convolution with inside-out information: discover what convolution is, why it is important and how it works. Enhance their FPGA design skills, i.e., enhance their FPGA-related prototyping capability with model-based hands-on examples. Rapidly expand their digital signal processing (DSP) blocks: to examine how to rapidly and efficiently create (DSP) functional blocks on a programmable FPGA chip as a reusable intellectual property (IP) core. Upgrade their expertise as both thinkers and doers: minimize/close the gap between mathematical equations and FPGA implementations for existing and emerging wireless applications.
