Abstract
A communication device includes: a reception unit that receives a signal transmitted from another communication device via a transmission path; a transmission unit that transmits a signal to the another communication device via the transmission path; an error rate measurement unit that measures an error rate representing a probability of occurrence of errors in a signal received by the reception unit in a case where a bi-directional communication with the another communication device is performed; and a phase adjustment unit that adjusts a phase of a signal transmitted from the transmission unit to the another communication device based on an error rate measured by the error rate measurement unit.
Claims7
A communication device comprising:
- a reception unit that receives a signal transmitted from another communication device via a transmission path;
- a transmission unit that transmits a signal to the another communication device via the transmission path;
- an error rate measurement unit that measures an error rate representing a probability of occurrence of errors in a signal received by the reception unit in a case where a bi-directional communication with the another communication device is performed;
- and
- a phase adjustment unit that adjusts a phase of a signal transmitted from the transmission unit to the another communication device based on an error rate measured by the error rate measurement unit.
A communication system comprising:
- a transmission path that couples a first communication device with a second communication device, and through which the first communication device and the second communication device transmit signals bi-directionally;
- a first reception unit that receives a signal transmitted from the second communication device via the transmission path;
- a first transmission unit that transmits a signal to the second communication device via the transmission path;
- and
- a first error rate measurement unit that measures a first error rate representing a probability of occurrence of errors in a signal received by the first reception unit in a case where a bi-direction communication with the second communication device is performed, wherein
- the first transmission unit includes:
- the first communication device that transmits the first error rate to the second communication device;
- and
- the second communication device, and
- the second communication device includes:
- a second reception unit that receives a signal and the first error rate transmitted from the first communication device via the transmission path;
- a second transmission unit that transmits a signal to the first communication device via the transmission path;
- a second error rate measurement unit that measures a second error rate representing a probability of occurrence of errors in a signal received by the second reception unit in a case where a bi-directional communication with the first communication device is performed;
- and
- a phase adjustment unit that adjusts a phase of a signal transmitted from the second transmission unit to the first communication device based on the first error rate and the second error rate.
