Some measure of the received signal strength. > 2. Where can we get the information? I'm assuming when the > daughterboards are initialized most of this information is available. For the time being, assume that you are getting it from the "Post ADC" rssi block, rssi.v. See also usrp_std.v (search for rssi). > 3.

The representation can be manipulated on the host. > Thanks! > George Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
