Hi,
I was trying to use the OFDM Mod block to create a OFDM signal with FFT
size=8192, occupied tones=6818 and CP=2048
However I keep getting this error:
File "/usr/local/lib/python2.7/dist-packages/gnuradio/digital/ofdm.py",
line 106, in __init__
padded_preambles)
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/digital/digital_swig.py",
line 4517, in ofdm_insert_preamble
return _digital_swig.ofdm_insert_preamble(*args, **kwargs)
RuntimeError: digital_ofdm_insert_preamble: invalid length for preamble
symbol
If I use a lower number of occupied tones this error disappears but I was
interested in this number because it is close to the DVB-T 8k mode.
Can you explain me what am I doing wrong or if there is a workaround for
this problem
Thank you and Regards,
Francisco
