We analyze low density parity check codes that correct both errors and erasures using a simple decoding scheme. Our framework unifies previous analyses for low density parity check codes and erasure codes. The result is a general class of codes that corrects both errors and erasures, with corresponding simple linear time encoding and decoding algorithms and provable performance guarantees. We a...
