Simulation of UWB Distortion Combined with Indoor Spatio- Temporal Channels

نویسنده

  • K. Makaratat
چکیده

The modified aspects for simulating UWB multipath channels are presented in this paper. Pulse distortion mechanisms based on the geometric optics and the geometric theory of diffraction are specifically generated combing with the spatio-temporal characteristics of multipath clusters based on 3x3 planar array systems. In each particular scenario, model parameters such as angle-of-arrival, angle-of-departure and time-of-arrival are statistically synthesized, corresponding to cluster groups along the propagation paths. Furthermore, characteristics of frequency dependence of propagation channels simulated over 10 frequency subbands (2-11 GHz) with 1 GHz bandwidth are also analysed.

Double Directional Ultra Wideband Channel Characterization in a Line-of-Sight Home Environment

This paper introduces the concept of measuring double directional channels in ultra wideband (UWB) systems. Antennaindependent channel data were derived by doing the measurements in a wooden Japanese house. The data were useful for investigating the impact of UWB antennas and analyzing waveform distortion. Up to 100 ray paths were extracted using the SAGE algorithm and they were regarded as bei...

بهبود کارآیی سیستم UWB مبتنی بر TiR در شرایط تخمینگر غیر ایده آل کانال

In this paper, we improve the performance of the TiR-UWB communication systems with the non-ideal estimation of the channel. Time Reversal (TiR) technique is an effective and simple method for data transmission in extremely multipath indoor UWB channels that mitigates the complexity of receiver by its own time focusing feature. Although, TiR method has the suitable performance, but it is sensit...
