Distance Spectrum of Fixed-Rate Raptor Codes with Linear Random Precoders
Francisco Lázaro, Enrico Paolini, Gianluigi Liva +1
Raptor code ensembles with linear random outer codes in a fixed-rate setting are considered. An expression for the average distance spectrum is derived and this expression is used…
Inactivation Decoding Analysis for LT Codes
Francisco Lázaro, Gianluigi Liva, Gerhard Bauch
We provide two analytical tools to model the inactivation decoding process of LT codes. First, a model is presented which derives the expected number of inactivations occurring in…
Protograph-Based LDPC Code Design for Shaped Bit-Metric Decoding
Fabian Steiner, Georg Böcherer, Gianluigi Liva
A protograph-based low-density parity-check (LDPC) code design technique for bandwidth-efficient coded modulation is presented. The approach jointly optimizes the LDPC code node de…
On The Weight Distribution of Fixed-Rate Raptor Codes
Francisco Lázaro, Enrico Paolini, Gianluigi Liva +1
In this paper Raptor code ensembles with linear random precodes in a fixed-rate setting are considered. An expression for the average distance spectrum is derived and this expressi…
