# Example of coding using a (7,4) Hamming code, with transmission through
|
|
# a Binary Symmetric Channel with error probability of 0.05.
|
|
#
|
|
# This example shows how random source messages can be encoded as codewords,
|
|
# transmitted through the simulated channel, decoded, and the message bits
|
|
# extracted from the codewords. The final result is in ex-ham7b.ext, which can
|
|
# be compared to ex-ham7b.src.
|
|
|
|
set -e # Stop if an error occurs
|
|
set -v # Echo commands as they are read
