Hi Sara,
when looking into the "Instrumentation" Category in the Companion, you
will notice two subcategories with several different visualization types.
On many of these, you can set a number of input ports.
Greetings,

Thanks Marcus .
I want to append 2 plots on same graph ( the transmitted signal and the
received signal ) . I connected WX GUI scope sink to the ofdm tx and
another one to the ofdm rx . I put CFO model & channel model between the tx
& rx . I want to compare between the signals while changing offse
Hello Sara,
It's hard to tell without you offering us the actual line where you call
make, but from looking at your symbols variable I'd say you have a tuple
containing a tuple of tuples of floats,
and what you need would be a
tuple of tuples containing complexes.
Note that (1,1j) is *not* a comp
Hello ,
I want to implement ofdm system with these parameters:
FFT length=128
Occupied subcarriers=117.
4 pilots
1 DC
6 zeros subcarriers .
I put these parameters in ofdm tx & ofdm Rx:
Occupied carriers =(range(-58,-42)+range(-41, -14) + range(-13, -7) +
range(-6, 0) + range(1, 7) + range(

It's definitely possible. The main question is how to design

No, not in the current implementation. You'll have to create a new
ofdm_modulator block to handle this behavior.
Thanks a lot
Another question: It's possible to have adaptive modulation, that is the
possibility to use different modulation for any subcarrier?

Is it possible that fft_length= occupated carrier (--occupied-tones in
blksimpl/ofdm.py) + un_used carrier ? Where can i set the position of
the occupated_bins?

To modify the bandwidth, you have to set the interpolation and
