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.

System and method for full duplex cancellation

Low bit-rate feedback wireless communication systems with reduced computational complexity is described. A first set of information is obtained and mapped to a set of regions. Each region of the set of regions has at least one portion with a zero value. The at least one portion is selected from a group consisting of an imaginary portion and a real portion. A second set of information is provided responsive to the mapping and stored for access by at least one component of the wireless communication system.
