Generally the synchronizers should converge faster than that, especially for high SNR. 200 symbols is a very long time. Try tuning the loop more aggressively, or reducing the maximum deviation. Very short preambles (or very tight SNR requirements) may require a custom data-aided synchronization algorithm. --n > > Thanks, > Adeel > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > > _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
