Method and system for antenna interference cancellation
TL;DR: In this paper, a cancellation device can suppress antenna interference by generating an estimate of the interference signal and subtracting the estimate from the interference signals, based on sampling signals on an antenna that generates the interference or on the antenna that receives the interference.
