Power and sub-channel optimization of JPEG 2000 image transmission over OFDM-based cognitive radio networks

作者:

Highlights:

• A new unequal power and channel allocation algorithm is proposed for transmission of JPEG 2000 images over cognitive radio systems.

• The proposed algorithm enhances the average PSNR significantly for multipath channels.

• The algorithm can be implemented in real time.

• The scheme can be generalized to other standards such as JPWL
