Thresholds of Braided Convolutional Codes on the AWGN Channel

Farooq, Muhammad Umar LU ; Moloudi, Saeedeh LU and Lentmaier, Michael LU (2018) 2018 IEEE International Symposium on Information Theory, ISIT 2018 2018-June. p.1375-1379
Abstract

In this paper, we perform a threshold analysis of braided convolutional codes on the additive white Gaussian noise (AWGN) channel. The decoding thresholds are estimated by Monte-Carlo density evolution techniques and compared with approximate thresholds from an erasure channel prediction. The results show that, with spatial coupling, the predicted thresholds are very accurate and quickly approach capacity if the coupling memory is increased. For uncoupled ensembles with random puncturing, the prediction can be improved with help of the AWGN threshold of the unpunctured ensemble.
