This book presents the development of Ultra Wideband (UWB) technology, its standardisation, UWB pulse parameters, different UWB transceiver architectures and its applications. Wireless Sensor Networks (WSN) is one such application where UWB technology can be employed. The WSN applications demand portability and ultra low power consumption from its components. UWB impulse radio transceiver, which is one of the suitable architectures for WSNs, uses coherent reception and digital domain pulse correlation. The current UWB receiver uses significant hardware parallelism in the digital backend....
