DEVICE FOR DECREASING INTERFERENCE IN CABLE BUNDLE AND METHOD THEREOF

摘要

Disclosed is a device and method for decreasing interference in a cable bundle. The device includes a plurality of concentration devices, an interference measurer, and a concentration device. Each concentration device accesses an uplink and provides a network service to a terminal through a cable bundle in an access section. An interference measurer is connected between the cable bundle and the terminal. The interference measure is configured to measure an interference signal by measuring a signal transmitted to the terminal through the cable bundle, calculate an interference coefficient for generating a quasi-interference signal, and transmit the same to the concentration devices. The concentration devices is configured to calculate an additional signal for offsetting an interference signal by using the interference coefficient, add the additional signal to the original signal, and transmit the additional signal to the cable bundle.

1. A device for decreasing interference, comprising:
a plurality of concentration devices, each connected to an uplink and configured to provide a network service to a terminal through a cable bundle in an access section; and an interference measurer connected between the cable bundle and the terminal and configured to measure an interference signal occurring between original signals by measuring a signal transmitted to the terminal from the plurality of concentration devices through the cable bundle, calculate an interference coefficient for generating a quasi-interference signal for offsetting the measured interference signal, and transmit the same to the concentration devices, wherein the concentration devices is configured to calculate an additional signal for offsetting an interference signal generated in the cable bundle by using the interference coefficient provided by the interference measurer, add the additional signal to the original signal to be transmitted to the terminal, and transmit the additional signal to the cable bundle.
