摘要： Disclosed herein are systems, methods, and computer-readable storage media for enabling improved cancellation of self-interference in full-duplex communications, or the transmitting and receiving of communications in a single frequency band without requiring time, frequency, or code divisions. The system estimates the signal strength and phase of a self-interference signal, generates a cancellation signal based on this estimate, then uses the cancellation signal to suppress the self-interference before sampling received analog signal. After applying the cancellation signal, the system samples and digitizes the remaining analog signal. The digitized signal is then subjected to additional digital cancellation, allowing for extraction of the desired signal.

摘要： Disclosed herein are a systems and method for using frequency tones to schedule full-duplex communications between at least two full-duplex communication nodes. Communication nodes having data to transmit send, as part of two contention rounds, two separate and randomly selected frequency tones. In the first contention round, all nodes having data to transmit simultaneously transmit a frequency tone. Based on these first frequency tones, groups of nodes are formed. Each group of nodes in turn transmits a second set of frequency tones, and a schedule of full-duplex communications is created based on the second frequency tones.
