Serial Schedules for Belief-Propagation: Analysis of Convergence Time
Abstract--Low-Density Parity-Check (LDPC) codes are usually decoded by running an iterative belief-propagation algorithm over the factor graph of the code. In the traditional messa...

Exchange of Limits: Why Iterative Decoding Works
We consider communication over a family of binary-input memoryless output-symmetric channels using lowdensity parity-check codes under message passing decoding. The asymptotic (in ...

Run-Time Parallelization of Irregular DOACROSS Loops
Dependencies between iterations of loop structures cannot always be determined at compile-time because they may depend on input data which is known only at run-time. A prime examp...
