Abstract
Although the signal-to-interference power ratio (SIR) based criterion for diversity reception has been highlighted in the literature as the most effective method for reducing the effects of cochannel interference, it is often not clear how to measure this parameter in a practical context. This work addresses the problem of finding a way to determine the level of interference (due to frequency reuse) from neighbouring cells in a mobile telephone system, with M-ary PSK modulated signals and fast fading channel. The proposed parameter measures the quality of the received signal corrupted by additive white noise and cochannel interference, for any number of interferers. It is also suitable for high bit rate transmission, as in indoor mobile radio systems, since the proposed method requires sampling the received signal at just one sample/symbol.
