<P>PROBLEM TO BE SOLVED: To obtain a receiver capable of effectively performing diversity reception even in correlation between antennas in a highly mobile flying object with rapid posture change. <P>SOLUTION: In a transmitter, one of branched transmission data is delayed by a delay part 11 and then inputted to a spread part 13-2. Spread parts 13-1 and 13-2 spread input data by using different spreading codes and the spread output is synthesized and transmitted. In the receiver, respective signals received by the antennas 16-1 and 16-2 are inversely spread by using the different spreading codes by inverse spread parts 17-1 and 17-2. Also, a delay difference given to the transmission data is absorbed by a delay part 19, and then a switching part 20 selects and outputs either one of the input signals. <P>COPYRIGHT: (C)2007,JPO&INPIT |
