Implementing Full Duplexing for 5G

This book examines the current state of the art in developing full duplex (FD) systems in 5G LTE cellular communications. The book also considers what can be achieved with ferrite-based circulators in terms of size reduction and performance enhancement, especially at millimetric frequencies. The relative merits of ferrite and non-ferrite circulators are compared in terms of their fundamental materials and device technologies, such as isolation, insertion loss, bandwidth and non-linearity. FD in the entire 5G cell is also examined and its resulting range of equipment and device communication. This includes front-hauling, more sophisticated back and front-hauling, backhaul beam switching, and cell extenders and relays, all of which could involve FD.
