Actually, it may. Imagine you decimate by a factor of 4, that's sort of like adding every 4 samples together -- amplitude grows by 4. Now, I think there is (or there ought to be) some code that, at lower decimation levels, shifts which bits of the register it outputs (presumably, takes 2 more significant bits) to keep the amplitude constant, but that code may not be there in your new version, or the FPGA might do it differently that I imagine. > I agree that the decimation has affected what looks like the frequency, > but otherwise it should look the same and not affect my ability to > decode it. Something else seems different between test_usrp_standard_rx > and the GMSK receiver. If the decimation factor is not correct there's no way it's going to work. - -Dan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHaDWoy9GYuuMoUJ4RAqA+AKCxTe9CwmLMa+Q78nDQbVclZFeSLQCgzixz s69aw69eVhxAf4j2cy1NUmo= =MpH6 -----END PGP SIGNATURE----- _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
