Method and apparatus for interference cancellation by a user equipment

摘要

An apparatus for interference cancellation includes: a front end processing circuit, for receiving at least an interference signal and a desire signal; an inner processing circuit, for channel/noise estimation and for suppressing the interference signal; and a MIMO (multi-input multi-output) processing circuit, for blindly detecting an interference parameter of the interference signal based on the suppressed interference signal, and for jointly cancelling the interference signal from the desire signal and for demodulating the desire signal based on the detected interference parameter and the channel/noise estimation from the inner processing circuit.

1. An apparatus for interference cancellation comprising:
a front end processing circuit, for receiving at least an interference signal and at least a desire signal; a microprocessor, for receiving a number of the interference signal and a number of the desire signal, identifying a MIMO ability parameter to inform about a number of channels/noise to be estimated, and informing about the number of the interference signal and the number of the desire signal to be processed; and an inner processing circuit, for receiving the MIMO ability parameter, performing channel/noise estimation on the interference signal and the desire signal and for suppressing the interference signal; and a MIMO (multi-input multi-output) processing circuit, for receiving the information about the number of the interference signal and the number of the desire signal to be processed, blindly detecting an interference parameter of the interference signal based on the suppressed interference signal, and for jointly cancelling the interference signal from the desire signal and demodulating the desire signal based on the detected interference parameter and the channel/noise estimation from the inner processing circuit.
