DYNAMIC BANDWIDTH ALLOCATION SYSTEM OF WIBRO/WIMAX COMMUNICATION

摘要

A dynamic bandwidth allocation system of WiBro/WiMAX communication methods are provided to control allocation of dynamic bandwidth through one BPF selected among BPF(Band Pass Filter)s, thereby quickly coping with a changed channel environment in real time. A frequency conversion unit(120) performs frequency down conversion of a channel signal. BPFs of a BPF unit(130) pass the down converted channel signal. A signal conversion unit(150) converts the channel signal into a digital signal. A switch unit(140) switches a selective operation about the BPFs. A processing unit(160) controls driving of the switch unit to transceive information only through the optimized BPF.
