Abstract

The present disclosure provides a communication system. The communication system includes a radio wave receiver; a transmission node that transmits data; and a reception node that receives the data from the transmission node. The transmission node changes a transmission rate of the data so that a notch point at which a spectrum of a communication waveform decreases overlaps with a frequency selected by the radio wave receiver.

First claim

The invention claimed is:

1. A communication system comprising:
a radio wave receiver;
a transmission node that transmits data; and
a reception node that receives the data transmitted from the transmission node, wherein
the transmission node changes a transmission rate of the data so that a notch point at which a spectrum of a communication waveform decreases overlaps with a frequency selected by the radio wave receiver.

2. The communication system according to claim 1 , wherein
the frequency selected by the radio wave receiver is defined as X megahertz,
the transmission rate of the transmission node is defined as Ya megabits per second, and
the transmission node changes the transmission rate to satisfy X is equal to integral multiple of Ya.

3. The communication system according to claim 2 , wherein
the transmission node changes the transmission rate to satisfy X=Ya.

4. The communication system according to claim 1 , wherein
the transmission node notifies the radio wave receiver of change completion information upon completing a change of the transmission rate.

5. The communication system according to claim 4 , wherein,
when the frequency is changed, the radio wave receiver starts and continues a muting process until receiving the change completion information from the transmission node.

6. The communication system according to claim 1 , wherein
the transmission node adds transmission rate information indicating the transmission rate after change to the data to be transmitted to the reception node, and
the reception node changes a receiving rate of the data based on the transmission rate indicated by the transmission rate information.

7. The communication system according to claim 6 , wherein
the frequency selected by the radio wave receiver is defined as X megahertz,
the receiving rate of the reception node is defined as Yb megabits per second, and
the reception node changes the receiving rate to satisfy X is equal to integral multiple of Yb.

8. The communication system according to claim 7 , wherein
the reception node changes the receiving rate to satisfy X=Yb.

9. The communication system according to claim 6 , wherein
the reception node notifies the radio wave receiver of change completion information upon completing a change of the receiving rate.

10. The communication system according to claim 9 , wherein,
when the frequency is changed, the radio wave receiver starts and continues a muting process until receiving the change completion information from the reception node.

11. The communication system according to claim 1 , wherein
the reception node changes the receiving rate of the data based on the frequency selected by the radio wave receiver.
