SIGNAL PROCESSING UNIT, AND INTERFERENCE CANCELLATION METHOD, DEVICE, AND SYSTEM

摘要

Embodiments of the present invention relate to a signal processing unit, and an interference cancellation method, apparatus, and system. The interference cancellation system of the present invention includes a centralized cancellation unit and at least two signal processing units, where at least a part of signal processing units in the at least two signal processing units are configured to detect at least a part of user signals in all user signals input into the interference cancellation system and reconstruct the detected user signals; the centralized cancellation unit is configured to perform cancellation on reconstructed signals and the user signals input into the interference cancellation system; and the at least two signal processing units are configured to detect, according to a residual signal after the cancellation, the user signals input into the interference cancellation system and output the detected signals. The interference cancellation method, apparatus, and system in the embodiments of the present invention are advantageous to improvement of a gain of a user signal after interference cancellation.
