Abstract
Multi-level symbols generated by applying a Random Projection Code (RPC) to a source bit sequence are received at a receiver via a noisy channel. The received multi-level symbols are represented in a bipartite graph as constraint nodes connected via weighted edges to binary variable nodes that represent the source bit sequence. A decoder uses ZigZag deconvolution to generate constraint node messages as part of an iterative belief propagation to decode the source bit sequence from the received multi-level symbols.
