Enhanced Verification-Based Decoding for Packet-Based LDPC Codes Over Wireless Channels

In this paper, the authors apply the Enhanced Verification-based decoding Algorithm (EVA) for packet-based LDPC codes over wireless channels. Compared with the Verification Algorithm (VA) in the literature, the EVA algorithm enhances the verification condition thereby reducing the likelihood of false verification. The wireless channels in simulations are modeled by Binary Symmetric Channel (BSC) and Gilbert-Elliott (GE) channel. The numerical results indicate the proposed algorithm gives a superior performance but with only moderate computation increase compared with VA.
