Conventional half-duplex wireless systems rely on transmitting and receiving in non-overlapping time slots or frequency channels. Accordingly, time and frequency division duplexing are key enabling technologies to realize bidirectional communications between transmitting and receiving nodes in cellular and wireless local area networks. With increasing user demands, these conventional systems are challenged by meeting spectral efficiency, throughput and latency requirements. Full duplex (FD) communications, that is supporting concurrent transmission and reception in a single time/frequency channel, has the potential to improve the attainable spectral efficiency and throughput and reduce latency.

Due to recent advances in antenna hardware and signal processing techniques specifically in multiple input multiple output (MIMO) systems applied to radio frequency and baseband signals, self-interference (SI) suppression of 80-110 dB is becoming possible. This high level of SI suppression is enabled by employing techniques in the analog, digital, propagation and spatial domains. Indeed, combining directional communications and their capabilities of separating radio signals in the spatial domain with advanced SI suppression methods that operate in the analog and digital domains is attracting a large interest from the research and engineering communities.

Full-duplex radios facilitating simultaneous transmission and reception (STAR) enable new military communication applications as well. In addition to enhanced spectral efficiency, the STAR capability can provide a technical advantage for armed forces by enabling their radio transceivers to conduct electronic warfare while receiving or transmitting information signals in the same frequency band. Also, advancements in SI cancellation technologies are expected to improve the performance of continuous-wave radar systems in terms of operational range, since enhanced SI cancellation allows to increase the transmit power.

In addition to various wireless communication scenarios and applications, there are a couple of other segments that have adopted full duplex techniques, including SI cancellation. The cable distribution node standards have incorporated SI cancellation and echo cancellation as DOCSIS -FDX to improve upstream throughputs. The digital subscriber line specifications (such as G.FAST) are also considering such techniques for the next revision of the standard called G.mgFAST. Also, continuous-wave radars apply SI cancellation to prevent the transmitted signal from leaking directly into the receiver chain. SI may also be applied to acoustic signals, such as when hearing aids use blind SI cancellation to suppress acoustic feedback signals.

The purpose of this Special Issue of IEEE Wireless Communications Magazine is to provide an overview of the status of FD wireless and wireline communications, report recent advances and identify open research and development challenges.
