This chapter provides an introduction to the basic concepts of a wireless communication system. First, a simple point-to-point wireless link is considered and the key techniques at the transmitter and receiver that are required for a successful communication are discussed. The wireless medium being ...
Detailed tutorials are included on all major topics required to understand fundamental principles behind both the main sub-circuits required to design an RF transceiver and the whole communication system. Starting with review of fundamental principles in electromagnetic (EM) transmission and signal ...
