Hi, I noticed that TOSSIM uses the following formula to compute RSSI: rcv->strength = (int8_t)(floor(10.0 * log(pow(10.0, power/10.0) + pow(10.0, noiseStr/10.0)) / log(10.0))); (in CpmModelC.nc) I notice that this is adding the signal power (gain) and noise levels. I am wondering if this is a true reflection of the physical phenomenon--i.e., in the CC2420, when RSSI is computed (CC2420Packet.getRssi(packet)), do signal and noise strength contribute in an additive fashion? Are there any paper or documents that support this notion? I appreciate any response in advance.
Thanks, Tal _______________________________________________ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
