Gang - just committed latest attempts to gr-atsc 2.x in cvs, updating atsc_bit_timing_loop, fs_checker, equalizer and field_sync_demux. Using an off-the-air signal they pass data down to field_sync_demux, which just scans for a valid field sync and that's as far as it goes.
Anyway it's pretty tenuous - I'm not sure how to proceed. Will probably just let it percolate for a while and play around with sticking fprintf's here and there. The last one I put in fs_checker_naive produced this: >>> gr_fir_fff: using SSE Press Enter to StopFSC_naive: 511 pattern good, errors: 0 FSC_naive: 511 pattern good, errors: 9 !!! atsci_fs_checker_naive: PN63 error count = 37 FSC_naive: 511 pattern good, errors: 0 FSC_naive: 511 pattern good, errors: 0 FSC_naive: 511 pattern good, errors: 1 FSC_naive: 511 pattern good, errors: 0 FSC_naive: 511 pattern good, errors: 2 FSC_naive: 511 pattern good, errors: 16 FSC_naive: 511 pattern good, errors: 6 !!! atsci_fs_checker_naive: PN63 error count = 32 FSC_naive: 511 pattern good, errors: 0 I'm amazed that much works ;)) --Chuck _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
