        # Reference: - When the OFDM modem initially syncs, it often
	#              has residual freq offset that causes abnormally
	#              high LDPC decoder bit errors forthe first few
	#              seconds.  This leads to a high coded BER being
	#              reported for short duration tests.  This
	#              settles down after a few seconds, and we get
	#              the expected coded BER when averaging over
	#              longer periods (e.g. 60s). However this
	#              particular test is necessarily short due to the
	#              slow speed of the semihosting system.  It is
	#              therefore sufficient to check that the
	#              performance is similar to the x86 C version,
	#              rather than expecting a low coded BER for a
	#              short run.
