Two–Way Relaying Communications with OFDM and BICM/BICM-ID
… characteristics of wireless channels, fading and multipath dispersion also contribute strongly to detection errors. Therefore, this thesis is mainly concerned with designing transmission and detection schemes to provide good detection quality of TWRC while taking into account the negative impacts …

Optical wireless communication systems employing dual header pulse interval modulation (DH-PIM)
… electromagnetic interference and prevention from multipath fading. However, optical wireless systems are subject to multipath distortion and are governed by eye safety standards. Therefore, a modulation scheme is required that is capable of providing high speed and good immunity to multipath …

Terrestrial radio wave propagation at millimeter-wave frequencies
… properties. The measurement results include multipath dispersion, short-term variation and signal attenuation under different weather conditions. A design technique is developed to estimate multipath characteristics based on antenna patterns and site-specific information. Finally, indoor …

Experimental Investigation Of Ultrawideband Wireless Systems: Waveform Generation, Propagation Estimation, And Dispersion Compensation
… research. One key challenge is the increased multipath dispersion which results because of the fine temporal resolution. The received response consists of different components, which have certain delays and attenuations due to the paths they took in their propagation from the transmitter to …

Ultra-Wideband Channel Modeling using Singularity Expansion Method
… models do not account for all the identified dispersion mechanisms namely the frequency dispersion, the resonant dispersion and the multipath dispersion. The objective of this research is to model resonant dispersion based on the Singularity Expansion Method (SEM) and provide guidelines for …
