Abstract :
In this paper propagation of soft-output information through the Boolean logic circuits is considered. As the result, an implementation of log-likelihood ratio (LLR) algebra in Boolean logic mappings is presented. The consequence of this approach to the soft-output decoding of maximum transition run (MTR) codes and their utilization in iterative decoding has been simulated and evaluated over E2PR4 magnetic recording channel
