“…Faulty iterative decoding of LDPC codes was first studied in [6], where the Gallager A and sum-product algorithms are considered. Later studies also targeted the Gallager B algorithm [7]- [9], the minsum algorithm [10]- [12], as well as more general messagepassing algorithms [13], [14]. All of the aforementioned studies provide valuable insight into the limitations of LDPC codes under various decoding algorithms and fault models.…”

Abstract-We study faulty successive cancellation decoding of polar codes for the binary erasure channel. To this end, we introduce a simple erasure-based fault model and we show that, under this model, polarization does not happen, meaning that fully reliable communication is not possible at any rate. Moreover, we provide numerical results for the frame erasure rate and bit erasure rate and we study an unequal error protection scheme that can significantly improve the performance of the faulty successive cancellation decoder with negligible overhead.
