Method for cancelling inter-subcarrier interference and apparatus for the same |
摘要 |
Disclosed are a method for cancelling inter-subcarrier interferences and an apparatus for the same. The method according to an example embodiment may comprise dividing total available subcarriers into a plurality of sub-blocks, composing Alamouti code symbol pairs by mapping input symbols to subcarriers included in each of the plurality of sub-blocks, and performing inverse fast Fourier transform (IFFT) on the Alamouti code symbol pairs. Therefore, inter-subcarrier interferences due to frequency error between transmit antennas of a distributed antenna system or a cooperative transmission apparatus may be cancelled in the frequency selective fading channel environment. |

1. A method for cancelling inter-subcarrier interference, performed in a transmitting apparatus, comprising:
dividing total available subcarriers into a plurality of sub-blocks, wherein a number of the sub-blocks is determined according to characteristics of a channel between the transmitting apparatus and a counterpart receiving apparatus; composing Alamouti code symbol pairs by mapping input symbols to subcarriers included in each of the plurality of sub-blocks; and performing inverse fast Fourier transform (IFFT) on the Alamouti code symbol pairs. |
