For instance, for an 8 MHz channel the correction bandwidth is greater than 3 x 64/7 = 27.4 MHz.

Generate a single carrier at the channel central
frequency whose level equals the average
COFDM output power or is set to the maximum
available. This is intended for signal level
alignment
Internal generation of test TS using PRBS
sequences of length 15 or 23 embedded within
NULL packets as specified in document ETSI TR
101 290.
Map a PRBS sequence into constellation points
following the guidelines of document ETSI TR
101 290.
Inject bit errors at the input to the constellation
mapper (results in a non-zero CBER before the
Viterbi decoder) or
convolutional encoder (results in a non-zero
VBER after the Viterbi decoder).
