Interference in Wireless Communication Systems: Mitigation and Exploiting

The opportunity to transfer information from a location to another has always held a position of capital importance for the mankind. The relevance of telecommunications is uncontested due to countless reasons, spanning from philosophical to tactical. The increasing demand for high data rate services is the driving force of the scientific research in this area. In order to provide the final user with a fast and reliable service, many technical challenges have to be completed. For what concerns the physical layer of communications, increasing the data rate usually involves a detrimental effect on the reliability of the link. Theoretical bounds of reliable transmission has been derived for channels affected by additive white Gaussian noise (AWGN). The performance in AWGN channel is a useful benchmark, because wireless communication systems are usually affected by further problems. One of the most discussed impairments that heavily deteriorates the performance is the interference, which is the topic discussed here. This thesis embeds the most of the author's works during his Ph.D.~course. In particular, each section is or contains an excerpts of publications.
