Full-duplex communication refers to a communication system that allows for simultaneous two-way communication, where both parties can transmit and receive data at the same time. This is in contrast to half-duplex communication, where data can only be transmitted or received at any given time. Full-duplex communication can be achieved through various technologies such as frequency division duplexing (FDD), time division duplexing (TDD), or advanced signal processing techniques. This capability is useful in improving the efficiency and throughput of communication systems, as it allows for faster data transfer and reduced latency. Research in full-duplex communication focuses on developing new technologies, algorithms, and protocols to optimize the performance of these systems. Key challenges in this research area include mitigating self-interference, improving spectral efficiency, and enhancing overall system capacity. Overall, full-duplex communication holds great promise for enhancing the performance of wireless communication systems and enabling new applications in areas such as 5G networks, Internet of Things (IoT), and beyond.
