This chapter lists data used for DVB-T2 parameter validations.
E.1 T2-Frame
The following validations applies to the T2-Frame structure.
E.1.1 T2-Base
Tables E.1 and E.2 shows which Pilot Patterns that are allowed for a given combination of FFT
and Guard Interval. For table cells without any Pilot Patterns, the combination of FFT size and
Guard interval is not allowed.
