| Abstract(in English) | This paper proposes a novel transimission method for JPEG2000 image in MC-DS-CDMA taking account of the codestream structure. JPEG2000 image is corrupted by bit errors of important part of codestream in the conventional MC-DS-CDMA that transmits the serial-to-parallel converted codestream by turns. To solve this problem, we decide priority of JPEG2000's codestream and then transmit each codestream with different weights so that we can reduce bit errors in the important part. Also, we transmit some divided images which have different weights, and on the receiver we can restore the original image by filtering images based on the weights. Simulation results demonstrate that the proposed method can realize higher PSNR performance of JPEG2000 image than the conventional one. |
