N2 - H.264/AVC image compression standard improve the capacity of fitting the varying channels, which meets the demand of cognitive radio. So, adaptive H.264/AVC image compression and decompression were realized, combining spectrum sensing. Spectrum sensing was performed exploiting energy detection algorithm, and then the frequency bandwidth was calculated. The closed form of compression ratio, image resolution and image transmission rate was obtained. Image compression was performed according to some compression parameters got from above closed form. Base-DVICI scheme of image compression and decompression was proposed, including hardware and software design. The driver program of EMIF was accomplished to receive or send image data. Finally, adaptive image compression and decompression was completed, which proved feasibility of proposed scheme.
