Title:
SIGNAL TRANSMISSION/RECEPTION DEVICE AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3709639
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a signal transmission device/method for multiplexing the band width of information with the same frequency without enlarging the band width, improving frequency efficiency and realizing a mass radio communication system.
SOLUTION: This signal transmission device 10 multiplexes and transmits three different information TA, information TB and information TC from three transmitters 11A, 11B and 11C through three different routes PA, PB and PC by using a transmission antenna part 12. A signal reception device 20 receives three different information TA, TB and TC which are multiplexed and transmitted through the three different routes PA, PB and PC in receivers 22A, 22B and 22C by using a reception antenna part 21, and three different reception information RA, RB and RC are obtained.
