Abstract :
We consider windowed decoding of LDPC Convolutional Codes on the Binary Erasure Channel (BEC) to study the trade-off between the decoding latency and the code performance. We make some key observations about regular LDPC Convolutional code ensembles under windowed decoding and give modified constructions of these codes that allow us to efficiently trade-off performance for gains in latency.
