Binary erasure
Webthe binary erasure channel with erasure probability p. The encoder will send a string of n symbols that are all 0’s if W is 0, and all 1’s if W is 1. Encoder BEC Decoder W = 0 W = 1 0000:::00 1111:::11 0ee0:::e0 ee11:::1e W^ = 0 W^ = 1 The decoder sees a mixture of 0’s and e’s or a mixture of 1’s and e’s. It looks for the rst WebWe now introduce the second channel model called the Binary Erasure Channel. The channel description is the following. The input X to the channel is binary, but the output Y of the channel can take value zero, one, and e, where the output symbol e denotes erasure. Gamma is the parameter of the channel called the erasure probability, where gamma ...

WebN2 - In this letter we propose an efficient on-the-fly algorithm for maximum-likelihood decoding of Raptor codes used over the binary erasure channel. It is shown that our proposed decoding algorithm can reduce the actual elapsed decoding time by more than two-thirds with respect to an optimized conventional maximum-likelihood decoding.
