Detailed Description

cuts stream of DAB samples into symbol vectors

Parameters

fft_length	length of the output vectors - number of samples per symbol without cyclic prefix
cp_length	lengith of the cyclic prefix
symbols_per_frame	number of symbols in a DAB frame, without Null symbol
gap	If the gap is > 0, leave a gap at the end of the symbol, i.e. return some of the cyclic prefix instead of the end of the symbol

input: port 0: complex - actual data; port 1: byte stream with trigger signal indicating the start of a frame output: port 0: complex vectors - sampled data; port 1: byte stream with trigger signal indicating the start of a frame
