Hi, I'm trying to implement an OFDM modulator. I've almost done but I have a question: In the new version of the ofdm.py (the one included in the trunk version, under the "dab" folder) I have to pass two inputs to the ofdm_mod class: the first of 96 bytes (depending on the numbers of the carreers) is the data source and that is clear, the second of 1 byte is the "control signal (frame start)". What is this control signal? Have I to create it from the data source stream? Or is a parameter?
Thank you very much, Gianluca
