I think this is a misunderstanding. A complex baseband signal represents 1/fs bandwidth of spectral content which the USRP will modulate to the center frequency -> fc. To have a "real" signal is to leave half of your spectrum undefined. Is it symmetric about fc? or is it really a complex signal centered at fc+fs/4? -Josh _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
