CINR v. SINR?

[festis88]

I'm sorry in advance if this question is below the knowledge and skill level of this board.

What is the difference between Carrier to Interference-plus-Noise Ratio (CINR) and Signal to Interference plus Noise Ratio (SINR)? Are they the same thing, and if not, is one used to compute the other?

I have searched on Google, IEEE, and other sources and cannot find a definitive answer.

Thank you in advance for your help!

They are exactly the same. S or C to signify the signal in one case and carrier in the other are same thing.

SNR, CNR same thing
SINR, CINR same thing

i think that C is for pilot subcarrier ( if we are talking about broadband signal) .

so , SINR is measured for the whole signal and CINR is measured at pilot subcarrier .

Dear charan langton i need a conformation on the reply of qasim

thank you
