This paper describes a monolithic integrated transceiver chipset intended for impulse radio (IR) Ultra-wide band (UWB) applications including indoor communication and indoor localization. The chipset operates in the higher UWB band centered at 7.68 GHz and it is optimized for a pulse bandwidth of about 1.5 GHz. The average pulse repetition rate of 60 MHz and an octagonal pulse position modulation...
In this paper an impulse radio UWB transmitter and receiver IC for precision localization sensor network at longer ranges is presented. Fabricated from a commercial low cost 2 μ m GaAs HBT technology, the transmitter features high output peak power, high efficiency at a low power consumption. A variable output peak power up to 20 dBm is measured with a total power consumption of 15 mW. The receiver...
Ultra-Wideband (UWB) communication system provides high accurate localization due to the high multipath resolution capacity. For Ultra-Wideband (UWB) localization systems, time-based schemes namely Time of Arrival (TOA) and Time Difference of Arrival (TDOA) provide very good accuracy due to the high time resolution (large bandwidth) of UWB signals. Due to the inherent suitability and accuracy of time-based...
