Pass a multi-channel random signal through a binary symmetric channel. For a specified error probability, compare the error rate comparing the
Err port output for each channel.
Use the Open model button to open the
Set different BSC error probabilities for the individual channels of a multi-channel signal by defining the
Error probability as a row vector set to [
0.02 0.04 0.07 ].
Err port for the
Binary Symmetric Channel is a binary matrix whose dimensions matches the input signal.
Err contains the error results for each channel. Sum the elements of each column output in
Err individually to get the total number of errors introduced per channel. Dividing each total by the total number of samples sent per channel yields the bit error rate for each channel.
BER for channel 1: 2.02960e-02 BER for channel 1: 3.97430e-02 BER for channel 1: 7.00090e-02
The computed BERs are approximately equal to the probabilities set in the
Error probability parameter.
