PROBLEM TO BE SOLVED: To reduce a considerable deterioration in characteristics on a propagation path of high correlation in a spatial multiplex transmission method. SOLUTION: The signal transmission system for transmitting a signal from a transmitter 10 having a transmission antenna to a receiver 20 having a reception antenna, is provided with a propagation path estimating means 1 for estimating a propagation path estimate indicating a status of a propagation path between the transmission antenna and the reception antenna for each transmission mode designating the transmission antenna to be used for signal transmission, a communication capacity estimating means 2 for estimating communication capacity for each transmission mode from the propagation path estimate, a transmission mode determining means 3 for determining the transmission mode fulfilling desired communication capacity on the basis of the estimated communication capacity for each transmission mode, and a transmitting signal generating means 4 for generating a transmitting signal to be transmitted in accordance with the determined transmission mode.
