Abstract :
In a macrodiversity cellular system, switching radio links between base stations cannot be done instantaneously. Thus branch selection is usually based on the measurement of the slowly-varying local mean power rather than the rapidly-varying instantaneous signal power. We offer an exact mathematical model to analyze the performance of a local-mean-based macrodiversity cellular system in a shadowed-Rician (desired)/shadowed-Rayleigh (interfering) channel. We investigate the impact of both fading (Rician or Rayleigh) and shadowing in terms of co-channel interference (CCI) probability. We also present an analytical model to incorporate the effects of branch correlation on macrodiversity systems
