In this paper a reconfigurable ultra-wideband (UWB) impulse radio (IR) transmitter is presented. The IR signal is synthesized at an intermediate frequency (IF) by employing a multi-Nyquist digital-to-analog converter (DAC) with 12 bit resolution and

A compact symmetric discone antenna for the 3 GHz to 20 GHz frequency range is demonstrated. The antenna design is optimized for a good transient response with low angular dependency. This property reduces antenna distortions and simplifies antenna d

In this paper an approach for indoor localization based on already installed communication transceiver infrastructure is presented. Only marginal additional hardware is required to implement the localization functionality. The idea is to use a power

An ultra-wideband (UWB) software defined radio (SDR) implementation is presented. The developed impulse radio (IR) transceiver employs first order bandpass (BP) sampling at a conversion frequency which is four times the channel bandwidth. The subsamp

A symmetric compact discone antenna for the 3GHz to 20GHz frequency range is presented and characterized. The radiation pattern exhibits excellent frequency independence thanks to a careful theoretical and practical analysis of the radiated spherical

To investigate impulse radio (IR) communication transceivers, bit error rate (BER) measurements are typically performed by connecting an arbitrary waveform generator and a digitizing oscilloscope. In this paper a reconfigurable software defined radio

A theoretical approach is described to determine the equivalent isotropic radiated power (EIRP) of Ultra-Wideband (UWB) impulse radio (IR) transmitters with a very high accuracy. The EIRP is derived from the power spectral density (PSD) of an IR sign

Omnidirectional antennas are widely used for different Ultra-Wideband (UWB) applications like channel sounding or Impulse Radio (IR) Communication [1], [2]. A good choice for such applications are 3 dimensional biconical antennas as they exhibit a pe
