Linear Programming Decoding for Non-Uniform Sources and for Binary Channels With Memory
… that communication takes place over a memoryless channel and that the source is uniform. Here, we extend the LP decoding paradigm by studying its application to scenarios with source non-uniformity and to decoding over channels with memory. We develop two decoders for the scenario of non-uniform …

Error-correction on non-standard communication channels
… systems are poorly modelled by the standard channels assumed in the information theory literature, such as the binary symmetric channel or the additive white Gaussian noise channel. Real systems suffer from additional problems including time-varying noise, cross-talk, synchronization errors …

A POMDP framework for antenna selection and user scheduling in multi-user massive MIMO systems
We use a partially observable Markov decision process (POMDP) framework to design a resource allocation policy for downlink transmit beamforming at a multi-antenna BS that is equipped with a massive number of antennas and only a limited number of RF chains. Considering that channels evolve …

Time varying channel models for 5G mobile communication systems
… mobile users over time varying communication channels remains a shared obstacle. In this thesis, we contribute to these global efforts by providing further fundamental understanding of time varying channels in 5G mobile communication systems and overcome the obstacle. First, we reopen the door …

Vision-Enhanced Communications: On the Benefits of NLOS/LOS Knowledge in Wireless Systems
… system design. Many properties of the wireless channel, especially for mobile applications, are highly dynamic and easily observable using non-radio frequency (RF) sensors or RF sensors operating out-of-band (OOB) which we refer to as vision sensors. Using vision sensors to provide information …
