I always compute the signal strength at the final channel bandwidth, in software, whereas the RSSI in the FPGA code seems to be running at the raw ADC bandwidth--which can produce wildly different RSSI estimates than an estimate produced from your final channel bandwidth. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
