<p><P>PROBLEM TO BE SOLVED: To provide a signal transmission method capable of providing excellent system performance in wireless transmission under a variety of different moving conditions. <P>SOLUTION: A transmitter determines a current moving speed mode of a receiver based on feedback information from the receiver. The transmitter encodes a signal to be transmitted by using an encoding system in a coherent transmission mode when the moving speed mode is a low-speed moving mode, and encodes the signal to be transmitted by using an encoding system in a non-coherent transmission mode when the moving speed mode is a high-speed moving mode, to transmit the encoded signal to the receiver. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
