Unequal Error Protection for Image Transmission and Its Performance Analysis
Chunli Chen · Jisuanji fangzhen · 2008
A novel unequal error protection coding scheme was proposed using CRC and RCPT codes for image wireless real-time transmission by introducing judge controller between source coder and channel coder. The characteristics of compressed stream and channels were synthetically used in this scheme, and the performance was simulated in fading channels. Simulating results show that this scheme distinctly outperforms traditional equal error protection system, especially in low SNR and high compressed ratio situations. The SNR range in which the UEP scheme outperforms the EEP scheme becomes wider when the channels become more deteriorated.
