how can i measure the "average received CNR(carrier-to-noise ratio)" which is given by Mohamed-Slim Alouini and Andren Goldsmith in "capacity of nakagami multipath fading channels". We all know that we can measure the recieved CNR by transmitted CNR- channel loss. Can i calculate the average received CNR in the same way average received CNR= average transmitted CNR-loss? I mean do the average CNR for transmitter and the receiver have the relation that can be used in the received CNR and transmitted CNR? ill appreciate it for ur answers
The carrier-to-noise ratio is defined as the ratio of the received modulated carrier signal power C to the received noise power N after the receiver filters as follows:
CNR = C/N
When both carrier and noise are measured across the same impedance, this ratio can equivalently be given as follows:
CNR = (Vc / Vn)2
Where Vc and Vn are the Root Mean Square (RMS) voltage levels of the carrier signal and noise respectively.
C/N ratios are often specified in decibels (dB) or in term of voltage as the following two formulas' figures shown.
