# 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.
