A Unified Approach to Hybrid Coding.

Hybrid analog–digital coding has been used for several communication scenarios, such as joint source–channel coding of Gaussian sources over Gaussian channels and relay communication over Gaussian networks. In this paper, a generalized hybrid coding technique is proposed for communication over discrete memoryless and Gaussian systems, and its utility is demonstrated via three examples—lossy joint source–channel coding over multiple access channels, channel coding over two-way relay channels, and channel coding over diamond networks. The corresponding coding schemes recover and extend several existing results in the literature. [ABSTRACT FROM AUTHOR]
