Abstract

A method for setting a filter coefficient for a communication system, which adjusts a frequency bandwidth by setting a filter coefficient of a wireless communication system over a communication network, is provided. In the method, a wireless communication system that includes a controller having a filter coefficient database and a web server, and a Digital Signal Processing device requests a filter coefficient and attribute information related to a set target frequency bandwidth from a management terminal. The wireless communication system receives the filter coefficient and the attribute information from the management terminal and stores the filter coefficient and the attribute information in the filter coefficient database. The wireless communication system sets a frequency bandwidth of the digital signal processing device as a set target frequency bandwidth based on the stored filter coefficient and the attribute information.

Claims

1. A method for setting a filter coefficient for a communication system, comprising:

utilizing a modem box that includes a filter coefficient database and a web server to request a filter coefficient and attribute information related to a set target frequency bandwidth from a management terminal;

receiving the filter coefficient and the attribute information from the management terminal at the modem box and storing the filter coefficient and the attribute information in the filter coefficient database; and

utilizing the modem box to set a frequency bandwidth of a Digital Signal Processing device of a wireless communication system as a set target frequency bandwidth based on the stored filter coefficient and the attribute information.

2. The method of claim 1, wherein requesting the filter coefficient and the attribute information comprises:

utilizing the modem box to transmit a web page including status information and to display the web page at the management terminal; and

utilizing the management terminal to set the filter coefficient and the attribute information based on the displayed web page.

3. The method of claim 1, wherein storing in the filter coefficient database comprises setting a name of the filter coefficient received from the management terminal as a name of the filter coefficient to be stored by the modem box.

4. The method of claim 1, wherein storing in the filter coefficient database comprises setting a randomly generated character string as a name of the filter coefficient to be stored by the modem box.

5. The method of claim 1, wherein receiving and storing the filter coefficient and the attribute information comprises storing attribute information including a guard band of the filter coefficient.

6. The method of claim 1, wherein storing in the filter coefficient database comprises receiving information associated with whether a guard band of the filter coefficient is included from the management terminal.

7. The method of claim 1, wherein setting the set target frequency bandwidth comprises:

utilizing the modem box to transmit one or more filter coefficients that include the stored filter coefficient and attribute information, and displaying the filter coefficients at the management terminal; and

utilizing the modem box to set a frequency bandwidth corresponding to a single filter coefficient selected by the management terminal, from among the one or more filter coefficients that are displayed, as the set target frequency bandwidth.

8. The method of claim 7, wherein displaying the filter coefficients at the management terminal comprises displaying attribute information including names of the filter coefficients and frequency bandwidths associated with the filter coefficients.

9. The method of claim 7, wherein setting the set target frequency bandwidth further comprises utilizing the wireless communication system to delete one or more filter coefficients selected by the management terminal from among the one or more filter coefficients that are displayed, and to delete attribute information associated with the selected filter coefficients.
