I've posted some new OTA samples that include FM broadcast stations. Stations contain SCA (Subsidiary Communications Authorization) and RBDS (Radio Broadcast Data System). The RBDS system provides song title, artist, station callsign, and other basic information that is displayed on common automotive receivers. The RBDS signal is a 57KHz (3 x 19KHz pilot tone) sub carrier that is BPSK modulated at 1187.5 bps. This is an open standard that would be interesting to process.
I've also posted another GPS snapshot. I have some Octave (open source Matlab) that process the snapshots and provides PRN and doppler shift of the each GPS satellite. I'll post the scripts later this week. Finally, I have an updated NTSC snapshot of color bars. The original snapshots provided a couple weeks ago were of the wrong sideband. NTSC is a VSB system where the lower side band is attenuated below the video carrier. http://www.kd7lmo.net/ground_gnuradio_ota.html Also provided is an udpated script for the newest version of numarray (1.3.1): http://www.kd7lmo.net/ground_gnuradio_baseline.html Hope they are useful.... _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
