Abstract [en]

In this thesis, an unequal error protection scheme for transmitting JPEG2000 images over wireless channel is investigated. The rapid growth of wireless communication has resulted in a demand for robust transmission of compressed images over wireless networks. The challenge of robust transmission is to protect the compressed image data against the impairments of the radio channel, in such a way as to maximize the received image quality. However, for highly compressed images, it would be beneficial that regions of interest (ROI) are prioritized for interpretability. The thesis addresses this problem; investigating unequal error protection for transmitting JPEG2000 compressed images. More particularly, the results reported in this thesis provide guidance concerning the implementation of stronger error correction coding schemes (Golay code) for ROI and comparatively weaker coding (Hamming code) for non-ROI image spaces. Such unequal error protection can be utilized by the base station for transmitting JPEG2000-encoded images over next generation wireless networks.
