APPARATUS AND METHOD FOR SUPPORTING VARIOUS SYSTEM BANDWIDTH IN BROADBAND WIRELESS COMMUNICATION SYSTEM

摘要

According to an aspect of the present invention, there is provided a method for supporting various system bandwidths in a broadband wireless communication system, the method comprising the steps of: determining a system bandwidth through a primary preamble for frame synchronization transmitted by a base station; Determining an FFT size, a number of guarded subcarriers, and a number of subcarriers to be used corresponding to a system bandwidth; and setting an operation parameter of the modem according to the FFT size, the number of guarded subcarriers, and the number of subcarriers to be used.;
