I want to analyse the effects of temperature variations on SNR.
SNR in dB = Pr - N
Pr = Pt + G - L


I have calculated Noise using the equation of N = k*T*B*F

where k is boltzman's constant, B is the bandwidth, T is temperature and F is noise figure which is calculate by F = 1 + (T/290)

When noise was calculated and propagation losses, it gave me a very small range of SNR with negative values which affected the BER and capacity of the system giving me a binary symmetric channel.

Is there any alternative way in order to see the effect of temperature on noise and thus on SNR.

Thanks
Rahmah
