Abstract

The SNIR (Signal to Noise and Interference Ratio) is needed for: • Evaluation of receiver performance together with BER, especially in non-lab environments, where SNIR preconfiguration is not feasible. • Power control A simple block diagram of a CDMA communication system is shown in figure 1. There are not only exter- nal noise (N 0 ) and external interference (I) but also internal influences in a communication system. The internal influences mainly consist of:
