Document Type and Number:
Japanese Patent JP4844745
Kind Code:
B2
Abstract:
To enhance probability in which mutual frequency channels are matched to each other when the transmitting side and the receiving side of a radio communication machine switch the frequency channels.
On the transmitting side, channels 1-10 are switched in an ascending order (channels 1-10). On the receiving side, the channels 1-10 are switched every other number in the ascending order like 1, 3, 5, 7, 9; 2, 4, 6, 8, 10. In comparison with the conventional example of switching the channels 1-10 in a descending order (channels 10-1) on the receiving side, the probability in which both channels are matched to each other improves from 50% up to 90% even when transmitting and receiving channels are deviated.
