%X The paper presented a multi-parameter optimized joint source channel coding method (MPO-JSCC), combined with JPEG2000 and Turbo codes for image transmission. On the basis of conventional layered-rate allocation mechanism, also chose the interleave length and iterative decoding times dynamically, according to the importance of that quality scalable bitstream for image recovery. Introduced the error resilient tools JPEG2000 provided to improve the image reconstruction ratio at the receiving end. Compared to the approaches reported in the literature, the MPO-JSCC method gives better compression efficiency while having higher coding gain, and reduces the transmission power budget.
