Abstract :
In this paper, we investigate the decoding performance of spatially-coupled LDPC codes in the case of faulty memory bit-cells within the storage modules of the decoder. Our study characterizes error resilience, by measuring the BER degradation from such errors and we focus on the application of error mitigation techniques that further aid the inherent error resilience. In particular, we propose mitigation strategies based on the use of methods that consider the algorithmic significance of each bit-cell fault, such as MSB protection and self-correction of messages.
