> [ I/Q compensation ] There's some discussion in Razavi's "RF Microelectronics", section 5.2.2, and Kenington's "Software Defined Radio", section 5.3.1.1. The distinction you mention between DC and AC might come from this LO self-mixing business, a nonlinear effect, and indeed only at DC since it involves the LO mixing with itself at some random amplitude and phase. AC coupling would eliminate this artifact, but it would do nothing for the linear I/Q mismatch errors.
Maybe future versions of the dbsrx could have I/Q compensation parameters in the EEPROM. Or is something there already? Cheers, Peter _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
