A real valued zero-IF "universal" (modulation independent) receiver does not exist. I think you have the a demodulating receiver in mind that relies on symmetry in the baseband spectrum, like for AM. In this concept, "baseband" is the real valued audio baseband. For digital modulations it doesn't make sense. The real valued representation with IF at half of the one-sided signal bandwidth can be called "real baseband", in contrast to the "complex baseband". Same data size, same content, same bandwidth, just shifted in spectrum. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
