COMMUNICATION SYSTEM AND COMMUNICATION DEVICE
First Claim
1. A communication system comprising:
- a first communication device; and
a second communication device conduct wireless communication with the first communication device,wherein the first communication device comprises;
a first transmitter that transmits a signal to the second communication device, anda first transmission controller that controls the first transmitter,wherein the second communication device comprises;
a first receiver that receives the signal from the first communication device,a first reception controller that controls the first receiver,a signal processor that processes the signal received by the first receiver, anda determination part that determines whether the signal received by the first receiver is a normal signal,wherein, when transmitting a predetermined first signal, the first transmission controller divides the first signal into a plurality of segments to change a transmission frequency of the first transmitter in units of segments,wherein, when receiving the first signal, the first reception controller changes a reception frequency of the first receiver according to the transmission frequency of each segment,wherein the signal processor combines the segments of the first signal, andwherein the determination part determines whether the combined first signal is the normal signal.

Abstract
A communication system has a first communication device, and a second communication device conduct wireless communication with the first communication device. The first communication device has a first transmitter that transmits a signal to the second communication device, and a first transmission controller that controls the first transmitter. The second communication device has a first receiver that receives the signal from the first communication device, a first reception controller that controls the first receiver, a signal processor that processes the signal received by the first receiver, and a determination part that determines whether the signal received by the first receiver is a normal signal. When transmitting a predetermined first signal, the first transmission controller divides the first signal into a plurality of segments to change a transmission frequency of the first transmitter in units of segments.
