An image transmission system in MC-DS-CDMA with weight control

This paper proposes a novel method for transmitting JPEG2000 images in MC-DS-CDMA taking into account the codestream structure. In the conventional MC-DS-CDMA that transmits the serial-to-parallel converted codestream by turns, the JPEG2000 image is corrupted by bit errors of the important parts of the codestream. To solve this problem, we determine an order of priority of the JPEG2000´s codestream and then transmit each codestream with different weights in order to reduce bit errors in the important parts. Also, some divided images of different weights are transmitted, and on the receiver the original image can be restored by filtering the divided images based on the determined weights.
