<p>A method and a device for detecting interference. The method comprises: performing a channel estimation on a carrier channel to obtain a tap {h̃ j } of an impact response of the carrier channel; calculating an autocorrelation function rhõ H (tau)of the carrier channel according to the tap {h̃ j } of the impact response of the carrier channel; calculating an autocorrelation function rhõ Upsilon (tau) of a received baseband symbol; calculating an autocorrelation function rhõ G (tau) of interference or noise, wherein rhõ G (tau)=rhõ Upsilon (tau)-rhõ H (tau); detecting whether the equation rhõ G (tau)=0 is valid; if rhõ G (tau)=0, determining that no interference exists; if rhõ G (tau) <> 0, determining that interference exists.</p> |
