Baseband Receiver Design for Wireless MIMO-OFDM Communications, 2nd Edition

Chapter 1

Introduction

All wireless communication standards, both existing and under development, adopt or consider adopting orthogonal frequency-division multiplexing (OFDM) modulation plus multiple-input multiple-output (MIMO) techniques as the transmission scheme. It is clear that MIMO-OFDM has become the definitive transmission scheme in current and future wireless communication systems.

The pursuance of better ways of living has been instrumental in advancing human civilization. Communication services available at any time and place free people from the limitation of being attached to fixed devices. Nowadays, thanks to remarkable progress in wireless technology, affordable wireless communication service has become a reality. Mobile phones hook people up whenever and wherever they want. Digital audio and video broadcasting offers consumers high-resolution, better-quality, and even interactive programs. The devices are now thin, light, small, and inexpensive. Recently, smart phones capable of running multimedia and broadband applications have gained popularity and now account for a large share of the worldwide mobile phone sales. As shown in Figure 1.1, the digital baseband transceiver is an essential piece of such smart phones.
