Re: [Discuss-gnuradio] tx_ofdm.grc & rx_ofdm.grc output data

Hi Martin.

I used the default settings for the parameters.

The data I'm seeing is after de CRC.

Here's my payload output at the HPD:
----------------------------------------------------------------------
Tag Debug: HPD / Payload
Input Stream: 00
Offset: 1547 Source: n/a Key: frame_len Value: 17
Offset: 1547 Source: n/a Key: packet_num Value: 182
Offset: 1547 Source: n/a Key: packet_len Value: 800
Offset: 1547 Source: n/a Key: ofdm_sync_carr_offset Value: 0
Offset: 1547 Source: n/a Key: ofdm_sync_chan_taps Value:
#<uniform-vector>
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
Offset: 1555 Source: n/a Key: packet_len Value: 960
----------------------------------------------------------------------

My vector source argument is:
tagged_streams.make_lengthtags((packet_len,), (0,), length_tag_name)


Other stuff:

I changed the OFDM Frame Equalizer of the payload part:
From:
digital.ofdm_equalizer_simpledfe(fft_len, *header*_mod.base(),
occupied_carriers, pilot_carriers, pilot_symbols, 2).base()

To:
digital.ofdm_equalizer_simpledfe(fft_len, *payload*_mod.base(),
occupied_carriers, pilot_carriers, pilot_symbols, 2).base()

I added a Repack Bits block at the rx, just before the CRC, from 2 to 8
bits.

I uploaded a screenshot and the grc file here

Any help is really appreciated, thanks!
