This book brings together the fields of communication, signal processing, and embedded systems and circuits. These fields come together with a single design goal, a WLAN transceiver which combines analog and digital design, VLSI and systems design, algorithms and architectures, as well as design and CAD/EDA. This book focuses on the overall approach to design problems and design organization needed for transceiver design. It does not focus on one particular standard, such as IEEE 802.11a/g.
