Article
An in-depth treatment of impulse an radio ultra-wideband (IR-UWB) wireless system is provided reviewing theoretical background, proceeding with detailed implementation procedure, and finally giving simulation and test results. This is the first research and prototyping work to be published in the field of IR-UWB that operates in the 6–8 GHz band. T...

This paper describes a localization method for an IR-UWB (Impulse Radio Ultra Wideband) two-way ranging system developed for precise time-of-arrival measurements. The ranging system provides a time resolution of 275 ps, which allows precise indoor distance estimation with the accuracy of ±4 cm. In this work, a two-way ranging algorithm has been ext...

Detection performance of Impulse Radio Ultra wideband IR-UWB wireless communication was evaluated in noisy and dispersive channel environment. A polarity reception method was introduced which sets reference phase and does phase detection in relation to it. Simulation results confirm that the adopted detection scheme can achieve a packet error rate...

This paper describes a monolithic integrated single-chip transceiver intended for impulse radio (IR)-Ultra-wide Band (UWB) applications compliant to the IEEE 802.15.4a standard. The transceiver operates in the higher UWB band on four different channels, which fit into the European spectral mask (defined by the ECC). In accordance to the standard, s...
Article
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Regarding these qualities, it is comprehensible that there is an interest in the automation industry to use ultra wideband based wireless sensor nodes to replace wired systems, to save energy and to sav...

A digital baseband was designed and implemented according to the standard IEEE802.15.4a both in FPGA and as well as ASIC. The baseband supports data rates 850 Kb/s, 6.81 Mb/s and 27.24 Mb/s running at the clock speed of 31.2 MHz. The transmitter and receiver were tested by introducing various distortions to the signal being received. The baseband w...

Conference Paper
Full-text available
Design, simulation, implementation and performance of IR-UWB baseband conforming to IEEE802.15.4a are discussed. The baseband can support various data rates such as 850 Kb/s, 6.81 Mb/s and 27.24 Mb/s. The design and parameter selection were considered carefully taking into account all possible imperfections that IR-UWB high frequency signal can exp...
Conference Paper
This paper presents a monolithically integrated ultra wideband direct up conversion transmitter designed in accordance with IEEE 802.15.4a standard. The transmitter operates in the higher UWB band in eight communication channels. It supports the burst position and the binary phase-shift keying modulation schemes and provides a modulated impulse seq...
