Abstract
Provided is an apparatus for an interference signal cancellation of a central station. The apparatus includes: a communication unit; a storage unit configured to store a transmission signal of the central station received via the communication unit; and a signal processor configured to extract first time synchronization information (NCR) of a current time and second time synchronization information (NCR) included in an overlapping signal and calculate a difference value between the two time synchronization information, when the overlapping signal which is an overlapped signal of a terminal station is received on the same channel as a channel of the transmission signal of the central station, and to extract the transmission signal of the central station stored in a previous time in the storage unit based on the difference value and remove an interference signal included in the overlapping signal.
