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
