Graphical interface for simulation and analysis of LDPC block codes

Low density parity check (LDPC) codes are one of the error-correction codes more versatile, promising and important, and have been adopted in most of the current communication standards. Given the actual and future relevance of these codes, we have developed a graphical interface for simulation and performance analysis considering several factors that affect their encoding and decoding. Thus, this interface could be useful in the design process of these codes, and also as a teaching-learning tool on this topic. In addition to the description of the interface and the analysis of simulations, importance of LDPC codes and graphical interfaces is discussed, the set of parameters and criteria considered in the simulations are described and some improvements to the current interface are suggested.
