Adjacent Channel Interference Cancellation in Multi-Channel Systems

摘要

A method for adjacent channel interference cancellation may be disclosed, comprising collecting adjacent channel usage samples at a first time; assigning coefficient weights in an adjacent channel interference model based on the adjacent channel usage samples; determining whether a radio may be available for measuring current adjacent channel usage; adjusting coefficient weights based on the current adjacent channel usage; and canceling noise in an adjacent channel at a second time based on the coefficient weights. A radio frequency chain may be coupled to the output of the radio transceiver and configured to sample adjacent channel interference caused by the radio transceiver.
