I am having some issues with GNUradio when trying to use OFDM transmitter and reciever. I am vaguely following the example on the WiKi here is my flow chart:
I am struggling to get the correct values for the OFDM modules. I have tried multiple values for the Occupied Carriers and Sync Word.
Current values:
Occupied Carriers: (list(range(-26, -21)) + list(range(-20, -7)) + list(range(-6, 0)) + list(range(1, 7)) + list(range(8, 21)) + list(range(22, 27)),)
Sync Word 1&2: (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)
Pilot Carrier: ((-21, -7, 7, 21,),)
This program is not working and it gives the following error:
TypeError: __init__(): incompatible constructor arguments. The following argument types are supported:
1. gnuradio.digital.digital_python.ofdm_carrier_allocator_cvc(fft_len: int, occupied_carriers: List[List[int]], pilot_carriers: List[List[int]], pilot_symbols: List[List[complex]], sync_words: List[List[complex]], len_tag_key: str = 'packet_len', output_is_shifted: bool = True)

This is new territory for me so please ask if I can make any clarifications
