Hello all,
Negative SINR in dB implies more noise than signal. Lets look at two cases
Case 1
Assuming a 5MHz BW, SINR of 17.5 dB and NF of 9 dB
Sensitivity = KTB + SINR(dB) + NF (dB) = -84 dBm
Case2
If SINR = -1 dB,NF = 9 and BW of 5 MHz
Sensitivity= -99.5 dBm
Looking at both cases tells me sensitivity improves with a negative SNR which I dont understand.
Would appreciate if someone could please clarify.
Thanks
