SIGNAL TRANSMISSION APPARATUS AND METHOD USING UNIQUE ANTENNA TECHNIQUE IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed are a signal transmission apparatus and method using a unique antenna technique in a wireless communication system. The signal transmission apparatus according to one embodiment of the present invention relates to a signal transmission apparatus using a unique antenna technique in a wireless communication system furnished with a plurality (N) of antennae, comprising an antenna correlation estimate part that estimates correlation information among said antennae based on the signal received in a reverse direction channel, a group separation part that separates said plurality of antennae into antenna groups corresponding to the number (M) of transmission signals based on said estimated correlation information among the antennae and provides said information on said separated antenna groups, a gain adjustment part that adjusts the gain of each group antenna included in a said antenna group based on said separated antenna group information, and a signal transmission part that transmits the pertinent signal via said antenna group for which the gain of the individual group antenna has been adjusted.
