<P>PROBLEM TO BE SOLVED: To provide a transmitter, a communication system, a communication method, and a processor, capable of solving a problem in which transmission power of a base station device naturally increases due to the necessity of removing all MUIs in MU-MIMO LP and a part of MUIs in MU-MIMO THP with a linear filter. <P>SOLUTION: The transmitter, for transmitting respective different signals to a plurality of receivers, comprises: a filter calculation part to calculate a precoding filter corresponding to an equivalent propagation path matrix which is made by quasi-orthogonalizing a propagation path matrix of a receiver; a precoding part to calculate a multiplexed signal of signals addressed to the receiver based on the calculated precoding filter; and a transmitting part to transmit the multiplex signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
