Calculating uplink Eb/No from uplink SIR measurements

Eb/No assumptions form an essential part of 3G radio network planning and system dimensioning. The deployment of 3G networks means that it is now possible to validate theoretical Eb/No assumptions. Network logging tools usually record levels of SIR rather than Eb/No. This paper derives the mathematical relationship between uplink Eb/No and uplink SIR. Example SIR measurements are used to calculate example Eb/No figures. This is done for SIR measurements which have been recorded from a test bed with controlled propagation conditions.
