Abstract

In this talk, we address the problem of designing LDPC decoders robust to transient errors introduced by a faulty hardware. Under symmetric error models at a message level, we derive the noisy Density Evolution equations and propose a new interpretation of the functional Density Evolution threshold previously introduced. We show that under restricted decoder noise conditions, the functional threshold can be used to predict the convergence behavior of FAIDs under faulty hardware. In particular, we reveal the existence of robust and non-robust FAIDs and propose a framework for the design of robust decoders. We finally illustrate robust and non-robust decoders behaviors of finite length codes using Monte Carlo simulations.
