A Method for Constructing LDPC Codes with Low Error Floor

Abstract

This paper describes a novel Progressive Edge Growth (PEG) algorithm for constructing LDPC codes with minimized block error probability over the Binary Erasure Channel (BEC). The constructed codes provide superior performance and lower error floor compared to codes generated by previously known algorithms. Furthermore, an upper bound on the expected block error probability in the error floor region of the generated code is derived.
