Signal To Interference Ratio Calculator

Posted by Dinesh on

This calculator calculates the signal to interference ratio using cellular radio systems, broadcasting systems values.

The signal-to-interference ratio, also known as the carrier-to-interference ratio, 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.

Calculating Carrier to Interference Ratio

Formula:

SIR = Pr ÷ Pi

where,

Pr is the desired signal powerfrom the desired base station
Pi is the desired signal powerfrom the desired base station
SIR is signal-to-interference ratio
