Robust image transmission performed by SPIHT and turbo-codes [PDF]
Serbian Journal of Electrical Engineering, 2008 This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are
