Packet erasure channel
Encyclopedia
The packet erasure channel is a communication channel model where sequential packets are either received or lost (at a known location). This channel model is closely related to the binary erasure channel
.
An erasure code
can be used for forward error correction
on such a channel.
Binary erasure channel
A binary erasure channel is a common communications channel model used in coding theory and information theory. In this model, a transmitter sends a bit , and the receiver either receives the bit or it receives a message that the bit was not received...

Erasure code
In information theory, an erasure code is a forward error correction code for the binary erasure channel, which transforms a message of k symbols into a longer message with n symbols such that the original message can be recovered from a subset of the n symbols...

Forward error correction
In telecommunication, information theory, and coding theory, forward error correction or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels....
