PROBLEM TO BE SOLVED: To provide a data transfer system capable of automatically setting a data transfer rate for preventing inter-code interference from occurring even when a multi-path occurs.SOLUTION: A wireless microphone 1 includes: a transfer rate determination start part 14; and a detection signal transmission part 15. A receiver 2 includes: a detection signal reception part 23 for receiving a detection signal from the wireless microphone 1; and a delay detection part 24 for detecting the delay amount of the detection signal due to a multi-path. A transfer rate determination part 25 determines the optimal transfer rate in accordance with the delay amount of the detection signal, and transmits the transfer rate from a transfer rate transmission part 26 to the wireless microphone 1. The wireless microphone 1 compresses a voice signal by a voice signal processing part 12 in accordance with the transfer rate received by the transfer rate reception part 16, and transmits the voice signal from a voice signal transmission part 13 to the receiver 2.SELECTED DRAWING: Figure 1 |
