Abstract:
1. A method of cancelling interference in a wireless system, said interference introduced by an interfering signal causing reception of an interfered signal responsive to transmission of a desired signal, comprising: acquiring said interfering signal from a transmitter during or before transmission thereof in time or frequency domain; estimating a reception interference based on al least one previously received interfered signal by utilizing an adaptive filter configured to generate a plurality of coefficients based on at least one previously received interfered signal to which a cancellation signal been injected or summated, where said plurality of coefficients are used for generating the cancellation signal; generating an analog cancellation signal based on said acquired interfering signal in time or frequency domain and said reception interference; and injecting said analog cancellation signal into an interfered receiver receiving said interfered signal to reduce said interference therefrom.
