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
