# 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
