Abstract :
In this paper, we present a new approach for channel coding on unknown or time-varying channels. Given a family of possible channel characteristics, we define a multi-resolution channel code as a single channel coding codebook from which a collection of codes of increasing rates are extracted by choosing larger and larger nested subsets of the original set of codewords. We give an achievable rate region and a tight converse
