In coding theory and information theory, a binary erasure channel (BEC) is a communications channel model. A transmitter sends a bit (a zero or a one), and the receiver either receives the bit correctly, or with some probability $${\displaystyle P_{e}}$$ receives a message that the bit was not … See more The channel capacity of a BEC is $${\displaystyle 1-P_{e}}$$, attained with a uniform distribution for $${\displaystyle X}$$ (i.e. half of the inputs should be 0 and half should be 1). Proof By symmetry … See more If bits are flipped rather than erased, the channel is a binary symmetric channel (BSC), which has capacity See more • Erasure code • Packet erasure channel See more The BEC was introduced by Peter Elias of MIT in 1955 as a toy example.

http://www.infogalactic.com/info/Binary_erasure_channel WebThe 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 is between zero and one.

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.

WebJan 8, 2024 · Abstract: We study the application of polar codes in deletion channels by analyzing the cascade of a binary erasure channel (BEC) and a deletion channel. We show how polar codes can be used effectively on a BEC with a single deletion, and propose a list decoding algorithm with a cyclic redundancy check for this case.
