چکیده
Delay-Hopped Transmitted-Reference(DHTR) is an attractive scheme for Ultra-wideband(UWB) systems. It relieves the channel estimation and the synchronization problems, which simplifies the UWB system. This paper presents a platform developed at Delft University of Technology. The purpose of the platform is to supply a hardware environment to implement DHTR UWB components. It can emulate real UWB signals as inputs of our digital UWB receiver and make efficient use of a USB link between the hardware and the PC. This platform provides a flexible environment for exploring and testing the realization of novel digital receiver algorithms. Currently it is being used to implement acquisition and demodulation algorithms. The obtained results are promising.

Analytical Description of Signal Characteristics and Interference For Time Hopped UWB System
In this paper, signal and interference characterisation of Time Hopped Ultra Wideband (TH-UWB) systems is considered. Some special problems often neglected in theoretical studies are discussed, such as the bound between nearfield and farfield and the distortions of wave shape. The transmitted TH-UWB signal is shown to be a cyclostationary process, as is the interference caused by TH-UWB signal ...
متن کاملSignal Processing Model for a Transmit-reference Uwb Wireless Communication System
This paper presents a signal processing model for the delay-hopped transmit-reference ultra wideband communications system introduced by Hoctor and Tomlinson. In that paper, a single-user receiver based on a bank of correlators and a sliding window integrator was proposed. However, the radio propagation channel also introduces correlations, which have a significant effect not taken into account...

متن کاملClosed-Form Derivations of ISI and MUI for Time-Reversed Ultra Wideband
Through transmitter pre-filtering, a time reversed UWB system is capable if harnessing a multipath channel to achieve temporal and spatial focusing. Unfortunately, large RMS channel delay spread leads to significant intersymbol and multiuser interference. This paper presents closed-form expressions for self and multi-user interference for a UWB system utilizing a time-reversed approach. The inf...
