PROBLEM TO BE SOLVED: To provide an interference suppression transmitter and interference suppression transmission method by which a communication opposite party can obtain a signal eliminating the effect of a delay wave or interference with a simple configuration. SOLUTION: A channel estimate section 112 uses a signal demodulated by wireless sections 110, 111 to estimate a state of a channel used by mobile station devices (A) and (B). An SIR optimum arithmetic section 118 uses a channel estimate value by the channel estimate section 112 to calculate a coefficient used at signal conversion with an inverse matrix arithmetic operation. A signal conversion section 119 uses a coefficient from the SIR optimum arithmetic section 118 to apply linear conversion to a transmission signal with respect to each mobile station device. The wireless sections 120, 121 modulate each transmission signal after the linear conversion and transmit the modulated signal via antennas 108, 109 respectively.
