||Joint product code optimization for scalable multimedia transmission over wireless channels
||State-of-the-art systems for the transmission of images over wireless
channels generate an embedded bitstream and protect it with
a product code where the row code is a concatenation of an outer
cyclic redundancy check (CRC) code and an inner rate-compatible
punctured convolutional (RCPC) code, and the column code is a
Reed-Solomon (RS) code. In previous works, the product code was
optimized by searching for the best RS protection for each RCPC
code rate. We present a local search algorithm that jointly optimizes
the RS and the RCPC codes. Experimental results show that
our algorithm provides an approximately optimal solution, while
its time complexity is much lower than that of the previous works.
