+Calculate the bit error rate (BER) or the symbol error rate (SER) over a number of \
samples given by the window size. \ +The actual window size will start at size one \
and grow to the full window size as new samples arrive. \ +Once the window has \
reached full size, old samples are shifted out of the window and new samples shfited \
in. +
+The error block compares the input byte stream to the reference byte stream. \
+For example, the reference byte stream could be the input to a modulator, \
+and the input byte stream could be the output of a modulator.
+
+Each byte in the incoming stream represents one symbol. \
+The bits per symbol parameter is only useful for calculating the BER.
