Abstract
Disclosed are a method of cancelling inter-subcarrier interference in a distributed antenna system, and a device for performing the same. The method of cancelling the interference performed in a receiver includes: generating a first signal and a second signal by performing a fast Fourier transform (FFT) operation on a received signal received from a first transmission antenna and a second transmission antenna; acquiring first symbols by combining the first signal and the second signal; generating a first interference signal and a second interference signal based on the first symbols; generating a third signal by cancelling the first interference signal from the first signal, and generating a fourth signal by cancelling the second interference signal from the second signal; and acquiring second symbols by combining the third signal and the fourth signal.
