<October,2020> doc.: IEEE 802. 15-20-0294-00-04aa Proposed RX Sensitivity Based on IEEE802.15.4-2020[2], Receiver sensitivity can be calculated as follows. MR-FSK (FEC ON) [dBm] Rate [kbps] MR-FSK [dBm] Note 25 -94.0 -100.0 50 -91.0 -97.0 100 -88.0 -94.0 200 -85.0 -91.0 300 -83.2 -89.2 400 -82.0 -88.0 600 -80.2 -86.2 Proposed Submission Slide 7 Hafuka, Kuramochi, LAPIS Technology
<October,2020> doc.: IEEE 802. 15-20-0294-00-04aa Proposed RX Sensitivity Required C/N Sensitivity = Required C/N + 20LOG(BW)+ NF + N Required C/N = Sensitivity { 20 LOG(BW) + NF + N} = -80 { 60 + 10 -174 } = 24dB (Enough Margin) Where, Noise level N: -174dBm Receiver Noise Figure NF(Relaxed):10dB BW : 1000kHz Sensitivity : -80dBm Submission Slide 8 Hafuka, Kuramochi, LAPIS Technology
