Co-Channel Interference

  • Gordon L. Stüber


For cellular radio systems the radio link performance is usually limited by interference rather than noise and, therefore, the probability of link outage due to co-channel interference (CCI) is of primary concern. The chapter begins with various approximations for the incoherent power sum of multiple log-normally shadowed interfering signals. The approximations are compared in terms of their accuracy. Afterwards, the probability of outage for log-normal/multiple log-normal links is considered. The chapter goes on to consider the outage probability for Ricean/multiple Rayleigh links without shadowing. Such an outage analysis may be more appropriate for wireless local area networks. The same is done for log-normal Nakagami/multiple log-normal Nakagami links, and log-normal Ricean/multiple log-normal Ricean faded links, where the signals are affected by both fading and shadowing. Such an outage analysis is appropriate for cellular systems where the mobile stations happen to be stationary.
