Abstract
A device for detecting an interference signal includes an estimator configured to estimate a mean value of received signals output from an analog-digital converter (ADC), a filter configured to filter a low frequency band of the received signals using the estimated mean value to produce filtered received signals, a detector configured to detect, from the filtered received signals, interference signals using a coherent modulation scheme and a non-coherent modulation scheme, and a combiner configured to determine whether interference exists in a frequency channel in response to a result of the interference signal detecting using the coherent modulation scheme and the non-coherent modulation scheme, based on a preset condition.
