Is your real signal at a non-zero IF? If so, just multiply by a complex sinusoid to translate to baseband, then use existing code path. We come from the complex is simple school of signal processing... _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
