Improving the data rate versus distance in communications using ultra wide bandwidth technology, 2007

Abstract

Ultra-Wideband Communication is increasingly being considered as an attractive solution for high data rate short range wireless and position location applications. Current designs for UWB focus on a small number of modulation and pulse shaping schemes and antenna design techniques. As such, simple improvements should be investigated first to increase system range, such as better modulation schemes, channel coding, antenna types, and/or Rake receivers. More sophisticated designs should then be investigated. In this thesis we investigate the use of M-ary PPM modulation techniques using isotropic, dipole, and horn antennas to improve the data rates versus distance in communications using UWB technology, by means of using two different path loss models
