Abstract :
The error performance of the ensemble of typical LDPC codes transmitted over the binary erasure channel (BEC) is analyzed under iterative decoding. In the past, lower bounds on the error exponent were derived. In this paper a probabilistic upper bound on this error exponent is derived. This bound holds with some confidence level.
