hello,
i have created a flowgraph (fig_0.png) for a simple ofdm link but it works only in parts. the first row (random_source --> gt_gui_constellation_sink) works perfect but the entire rest does not.
now two questions:
1) stream_to_tagged_stream block: how looks this tagged stream? is there a header (is it called header?) in which i can find the key (pl) or a number (6) of the following bytes?
pl,byte0, byte1,...,byte5 or 6,byte0,byte1,...,byte5?
2) when i simulate the entire graph i get the following error message:
using volk machine: sse3_64_orc
floating point exception
any idea why? the my_qpsk_demod_cb block works perfect. it is from the guided tutorials 3+4 and tested.
thanks in advance!
