Wireless Communications Systems Design

Preface

The main purpose of this book is to help senior undergraduate students, graduate students, or young engineers design wireless communications systems by themselves. The basic architecture of wireless communications has not changed much in recent decades. Especially, most of the broadband wireless communications (WiMAX, LTE, WLAN, UWB, etc.) adopt similar techniques (OFDM/OFDMA, turbo codes/LDPC, MIMO, AMC, etc.). Therefore, this book is intended to provide the basic knowledge and methodology for wireless communications systems design. This book is based on my experience in various areas (standards, research and development) of wireless communications as a researcher, developer, and consultant.

Many different interests are entangled in the wireless communications systems design. The designed wireless communication system should satisfy various interested parties such as vendors, mobile operators, regulators, and mobile users. For example, in a wireless communication system, an officer of a regulatory agency will look for efficient spectrum usage and for violation of the regulation for the frequency band. A mobile operator will look out for business opportunities, service quality, and the cost of the infrastructure. A mobile phone vendor or a network equipment vendor looks for the cost-effective design of the wireless communication system. An end user is interested in whether or not it can use a network with enough data rates and seamless connection. In order to build ...
