On Generalized LDPC Codes for 5G Ultra Reliable Communication
Yanfang Liu, Pablo M. Olmos, David G. M. Mitchell
Generalized low-density parity-check (GLDPC) codes, where single parity-check (SPC) constraint nodes are replaced with generalized constraint (GC) nodes, are a promising class of c…
Probabilistic MIMO Symbol Detection with Expectation Consistency Approximate Inference
Javier Cépedes, Pablo M. Olmos, Matilde Sánchez-Fernández +1
In this paper we explore low-complexity probabilistic algorithms for soft symbol detection in high-dimensional multiple-input multiple-output (MIMO) systems. We present a novel alg…
Spatially Coupled Generalized LDPC Codes: Asymptotic Analysis and Finite Length Scaling
David G. M. Mitchell, Pablo M. Olmos, Michael Lentmaier +1
Generalized low-density parity-check (GLDPC) codes are a class of LDPC codes in which the standard single parity check (SPC) constraints are replaced by constraints defined by a li…
A Probabilistic Peeling Decoder to Efficiently Analyze Generalized LDPC Codes Over the BEC
Yanfang Liu, Pablo M. Olmos, Tobias Koch
In this paper, we analyze the tradeoff between coding rate and asymptotic performance of a class of generalized low-density parity-check (GLDPC) codes constructed by including a ce…
Continuous Transmission of Spatially-Coupled LDPC Code Chains
Pablo M. Olmos, David G. M. Mitchell, Dmitri Truhachev +1
We propose a novel encoding/transmission scheme called continuous chain (CC) transmission that is able to improve the finite-length performance of a system using spatially-coupled…
Finite-length scaling based on belief propagation for spatially coupled LDPC codes
Markus Stinner, Luca Barletta, Pablo M. Olmos
The equivalence of peeling decoding (PD) and Belief Propagation (BP) for low-density parity-check (LDPC) codes over the binary erasure channel is analyzed. Modifying the scheduling…
