Abstract
Embodiments of the present disclosure provide methods and apparatus for detection of radio signal. A method performed by a reception apparatus may comprise: obtaining (S) time domain samples of a radio signal; processing (S) the time domain samples by a plurality of match filters respectively, to generate a plurality of filtered results of the time domain samples; classifying (S) a filtered result of the plurality of filtered results by a classifier; discarding (S) a filtered result classified as being not associated to the code sequence; and determining (S) whether the code sequence is used in the radio signal, when a filtered result of the radio signal is classified as being associated to the code sequence. Some processing procedures may be avoided based on the classification result of the detected radio signal, and computational complexity may be reduced.
