We propose a factor-graph-based approach to joint channel-estimationand-decoding of bit-interleaved coded orthogonal frequency division multiplexing (BICM-OFDM). In contrast to ex...

This paper defines the basic notions of local and non-local tasks, and determines the minimum information about failures that is necessary to solve any non-local task in message-p...
