RECEIVER ADOPTING DIVERSITY SYSTEM, TRANSMISSION/RECEPTION SYSTEM ADOPTING DIVERSITY SYSTEM, AND SOUND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a receiver adopting a diversity system capable of enhancing reproduction sound quality in wireless audio visual and to provide a sound system.;SOLUTION: The receiver is provided with: a plurality of antennas 22 for receiving a transmission signal through which information is intermittently communicated as a form of block data by radio and outputting received signals respectively; an antenna switching section 23 for selecting one of a plurality of the received signals from a plurality of the antennas 22; a reception section 25 and a demodulation section 26 for demodulating a demodulation signal from the selected received signal and outputting the demodulated signal; an error confirmation section 30 for detecting an error state of the received signal; an AND/discrimination circuit 33 for activating the antenna switching section 23 in response to a result of the detection of the error confirmation section 30; and a block data timing discrimination/control section 29a operated by the AND/discrimination circuit 33 on the basis of an identification signal between the block data at the tail end of which the identification signal is included.;COPYRIGHT: (C)2006,JPO&NCIPI
