C/I

What is C/I?

Also known as

• C/I CIR Carrier To Interference ratio / S I R SignalToInterference
• C / I C I R CarrierToInterference / SIR Signal To Interference

What is C/I

C/I = Carrier To Interference

C/I or CIR or SIR or S/I is the quotient between the average received modulated carrier power S or C and the average received co-channel interference power I, i.e. cross-talk, from other transmitters than the useful signal.
