So we transmit … WebThe Err port for the Binary Symmetric Channel is a binary vector whose length matches the total number of samples processed. By summing the elements of the output Err vector you get the total number of errors introduced into the signal data. The sum of the elements of the Err vector is saved to the base workspace variable BscErrTotal.
