My explanation pertained to the benchmark_rx; but Johnathan already said it doesnt matter in his first reply ;) >Not sure what post you are referring to.

Different strategies in a receiver chain places the >frequency/phase synchronization at different places. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
