This paper proposes an interference suppression technique using a dynamic spectrum control (DSC) for distributed control based cognitive radio networks.
Based on the consideration that the CSMA/CA is not efficient in terms of throughput due to its strict collision avoidance process, this paper employs a DSC in which a certain number of discrete spectra having the highest channel gain is selected individually in each link allowing a partial band interference, and such interference is suppressed by the equalizer in the receiver. To further suppress mutual interference occurrence, a part of spectrum having relatively high interference level is also removed from the candidate of selectable discrete spectra. Evaluation of channel capacity and system throughput by computer simulation conforms that the proposed scheme is effective in achieving high channel capacity and system throughput even under autonomous distributed control. |
