Study of Adaptive Reweighted Sparse Belief Propagation Decoders for Polar Codes

R. M. Oliveira, R. C. de Lamare

In this paper, we present an adaptive reweighted sparse belief propagation (AR-SBP) decoder for polar codes. The AR-SBP technique is inspired by decoders that employ the sum-produc…

Study of Design of Rate-Compatible Polar Codes Based on Non-Uniform Channel Polarization

R. M. Oliveira, R. C. de Lamare

We propose a novel scheme for rate-compatible arbitrary-length polar code construction for the additive white Gaussian noise (AWGN) channel. The proposed scheme is based on the con…

Study of Non-Uniform Channel Polarization and Design of Polar Codes with Arbitrary Rates

Robert M. Oliveira, Rodrigo C. de Lamare

In this paper, we present the concept of non-uniform channel polarization and a scheme for rate-compatible polar code construction for any codeword length using additive white Gaus…

Study of Polarization-Driven Shortening for Polar Codes Designed with the Gaussian Approximation

R. M. Oliveira, R. C. de Lamare

This paper presents a polarization-driven (PD) shortening technique for the design of rate-compatible polar codes. The proposed shortening strategy consists of reducing the generat…
