METHOD FOR ELIMINATING SIGNAL INTERFERENCE BASED ON MULTIPLE INPUT MULTIPLE OUTPUT

摘要

Provided is a method for eliminating a MIMO-based signal interference comprising: a step of transferring a reference signal to at least one receiver; a step of estimating channel information in the receiver, and receiving the estimated and feedback channel information; a step of generating a sending precoding matrix, a beam forming matrix, and a weighting matrix using the received channel information; and a step of including information including the beam forming matrix and the weighting matrix in a pilot signal, and transferring the information to the receiver.
