# These tests investigate what happens when the wrong model is used for
|
|
# decoding. A (1800,1000) LDPC code with 3 check per bit is used.
|
|
# Testing is done by transmitting random messages. Decoding is done using
|
|
# a maximum of 100 iterations of probability propagation.
|
|
#
|
|
# The first set of tests compares decoding of messages sent through an
|
|
# AWGN channel using the correct AWGN model with sigma=0.90 to decoding
|
|
# using AWGN models with incorrect values for sigma and to decoding
|
|
# using AWLN models with varying width parameters for the logistic noise
|
|
# distribution.
|
|
#
|
|
# A second set of tests compares decoding of messages sent through an
|
|
# AWLN channel using the correct AWLN model with width=0.50 to decoding
|
|
# using AWLN models with incorrect values for width and to decoding
|
|
# using AWGN models with varying sigma parameters.
