With more and more new multimedia rich services being introduced and offered to a rapidly growing population of global subscribers, there is an ever-increasing demand for higher data rate wireless access, making more efficient use of the precious resource a crucial need. As a consequence, new wireless technologies such as Long Term Evolution (LTE) and LTE-Advanced have been introduced. These technologies are capable of providing high speed, large capacity, and guaranteed quality-of-service (QoS) mobile services. With the technology evolution of cellular networks, new techniques, such as small cells, have also been developed to further improve the network capacity by effectively reusing the limited radio spectrum. However, all existing wireless communication systems deploy the half-duplex (HD) radios which transmit and receive the signals in two separate/orthogonal channels. They dissipate the precious resources by employing either a time-division or a frequency-division duplexing.

Full-duplex (FD) systems, where a node can send and receive the signals at the same time and frequency resources, can offer the potential to double spectral efficiency; however, for many years it has been considered impractical. This is because the signal leakage from the local output to input, referred as the self-interference, may overwhelm the receiver, thus making it impossible to extract the desired signal. How to effectively eliminate the self-interference has remained a long-standing challenge. Recently, there has been a significant process in the self-interference cancelation in FD systems, which presents a great potential for realizing the FD communications for the next generation cellular networks.
