Instanton analysis of Low-Density-Parity-Check codes in the error-floor regime
Abstract-- In this paper we develop instanton method introduced in [1], [2], [3] to analyze quantitatively performance of Low-Density-Parity-Check (LDPC) codes decoded iteratively ...

Amalgamated Generalized Low Density Parity Check and Luby Transform Codes for the Wireless Internet
– Luby Transform codes (LT) were originally designed for the Binary Erasure Channel (BEC) encountered owing to randomly dropped packets in the statistical multiplexing aided Inte...

Multilevel Structured Low-Density Parity-Check Codes
— Low-Density Parity-Check (LDPC) codes are typically characterized by a relatively high-complexity description, since a considerable amount of memory is required in order to sto...

Investigation of Error Floors of Structured Low-Density Parity-Check Codes by Hardware Emulation
Abstract−Several high performance LDPC codes have paritycheck matrices composed of permutation submatrices. We design a parallel-serial architecture to map the decoder of any str...

Construction of Near-Optimum Burst Erasure Correcting Low-Density Parity-Check Codes
In this paper, a simple and effective tool for the design of low-density parity-check (LDPC) codes for iterative correction of bursts of erasures is presented. The design method co...
