ABSTRACT:
In a transmitter2A, after an output level of a modulated signal is regulated by a first gain regulator5A, the signal is transmitted from a first antenna8A without delay, and after the modulated signal is delayed by a delay unit6A and an output level of the delay output is regulated by a second gain regulator7A, this signal is transmitted from a second antenna9A. Similarly, in a transmitter2B, after an output level of a modulated signal is regulated by a first gain regulator5B, the signal is transmitted from a first antenna8B without delay, and after the modulated signal is delayed by a delay unit6B and an output level of the delay output is regulated by a second gain regulator7B, this signal is transmitted from a second antenna9B. A receiver3receives the transmitted signals from the four antennas8A,8B,9A and9B via an antenna10, and executes a demodulation process.
