Wireless communications has become one of the fastest growing markets worldwide. This technology has become so pervasive that the electromagnetic spectrum it uses has become a scarce commodity. Practically all wireless communication systems today operate in half-duplex mode: the two communicating transceivers either take turns using the medium, or divide it into two disjoint frequency bands, in order to transfer information in both directions.In full-duplex mode, both transceivers receive and transmit on the same frequency band, simultaneously. The obvious advantage is that the spectral efficiency doubles. And yet, full-duplex is never used in practical systems.The reason lies in the resulting self-interference and the limitations of the electronic components the transceivers are built from. The signal from the transceiver’s own transmitter is many orders of magnitude more powerfulthan the desired signal from the other transceiver. Unfortunately, practical receivers have limited dynamic range, which makes it impossible to recover the desired signal.Very recently, a practical implementation of a full-duplex system was demonstrated, using a number of selfinterference cancelation techniques. This opened the door to the use of the full-duplex mode in many areas ofwireless communications, as is evident by the high number of recent publications on this topic.Of course, the performance of idealized full-duplex systems is known in some areas (e.g. relaying). However, virtually no work has yet been done on understanding realistic full-duplex radios, that offer obvious benefits,but also suffer from characteristic imperfections that are due to the way they are constructed.Here we are proposing a comprehensive study of how realistic full-duplex transceivers will affect all major forms of wireless communications. This includes traditional narrowband and wideband communications links,multiple-input, multiple-output (MIMO) systems, as well as cooperative wireless communications in the form of simple and two-way relays.We will model the imperfect full-duplex transceiver in order to understand its fundamental limitations as a function of its structure. We will then apply this knowledge to derive the benefits that such a radio can achieveover traditional half-duplex transceivers, and how to best exploit this. We will also give an answer to the question: what is a better use of extra hardware resources: MIMO or full-duplex, and under which conditions?Finally, we will model relay channels, both simple and two-way, using real full-duplex radios, and explain the benefits of these with respect to the traditional half-duplex relays.The theoretical and the experimental sides of this particular topic are inextricably connected. We have therefore planned a hand-in-hand treatment of the two, which will make our theoretical results more connected to reality, and allow us to experimentally verify all our results. Our testbed will also serve as an effective demonstrator of the full-duplex concept. Due to the fortunate timing, the highly focused objectives of the project, and the profound implications of the FD paradigm, very significant impact can be expected.
