Exploiting source redundancy to improve the rate of polar codes
2017
2017 IEEE International Symposium on Information Theory (ISIT)
We consider a joint source-channel decoding (JSCD) problem where the source encoder leaves residual redundancy in the source. We first model the redundancy in the source encoder output as the output of a side information channel at the channel decoder, and show that this improves random error exponent. Then, we consider the use of polar codes in this framework when the source redundancy is modeled using a sequence of t-erasure correcting block codes. For this model, the rate of polar codes can
