Abstract
Disclosed is a method of cancelling inter-subcarrier interferences in distributed antenna system. A method of cancelling interference performed in a transmitting station may include configuring a least one Alamouti pair by mapping subcarrier to each of input symbols, performing a 2N-point inverse fast Fourier transform (IFFT) on the at least one Alamouti pair, wherein the N is a natural number, and performing a frequency up converting on signals on which the 2N-point IFFT performed. Therefore, the inter-subcarrier interferences can be canceled efficiently.
