Abstract/Description:
Ultra-wide Band (UWB) has sparked a lot of interest lately from theindustry and academia. The growing capacity of the wireless industry is requires a new communication system that satis¯es the high data rate which does not interfere with existing RF systems. UWB promises to be this new technology. UWB also promises low power, low cost and °exibility. The UWB Channel opens up a huge new wireless channel with Giga Hertz Capacities as well as the highest spatial capacities measured in bits per hertz per square meter. When properly implemented UWB channel can share spectrum with traditional radio systems without causing harmful interference. In this thesiswe studied and compared several reduced complexity sub-optimal Ultra-Wide Band receivers. These receivers include auto correlation receiver, the square value detector and the absolute value detector are studied. We consider OOK and PPM modulation schemes. We examine these schemes and the receivers on Gaussian and UWB indoor channels. We compare the performance with optimal receivers.A transmitter receiver system using 0.1us pulses implemented usingexisting hardware. A packet consisting of 24 bits were transmitted and the received signal could be veri¯ed in real time using a vector signal analyzer. The results show sub-optimal receivers provide a better trade off between robust,complexity and performance.
