Multi-class source-channel coding. IEEE Trans Inf Theory. 2016 Jul 7;62(9):5093-104. DOI: 10.1109/TIT.2016.25884960018-9448http://hdl.handle.net/10230/35901This paper studies an almost-lossless source-channel coding scheme in which source messages are assigned to different classes and encoded with a channel code that depends on the class index. The code performance is analyzed by means of random-coding error exponents and validated by simulation of a low-complexity implementation using existing source and channel codes. While each class code can be seen as a concatenation of a source code and a channel code, the overall performance improves on that of separate source-channel coding and approaches that of joint source-channel coding when the number of classes increases.application/pdfeng© 2016 IEEE.
