Sparsity-Aware Wireless Networks: Localization and Sensor Selection

Wireless networks have revolutionized nowadays world by providing real time cost-efficient service and connectivity. Even such an unprecedented level of service could not fulfill the insatiable desire of the modern world for more advanced technologies. As a result, a great deal of attention has been directed towards (mobile) wireless sensor...

Wireless Transceiver Design for High Velocity Scenarios

This thesis is dedicated to transceiver designs for high data-rate wireless communication systems with rapidly moving terminals. The challenges are two-fold. On the one hand, more spectral bandwidth of the transmitted signals is required by future wireless systems to obtain higher transmission rates, which can result in the frequency selectivity...

Localization and Communication for UWB-based Wireless Sensor Networks

The great demand for location-aware wireless sensor networks (WSNs) motivates the research in this thesis. The unique characteristics of WSNs impose numerous challenges on localization and communication. In this thesis, we handle some key challenges and provide affordable solutions. Impulse radio ultra wideband (IR-UWB) is employed as the...

OFDM transmissions over rapidly changing channels

This thesis is dedicated to efficiently estimate and equalize time-varying channels in OFDM and single-carrier systems.
