Abstract :
Pilot symbol assisted modulation (PSAM) has been shown to give good performance in Rayleigh fading and additive noise. In cellular systems though, it is cochannel interference, more than noise, that limits the system. The authors present the first analytical investigation of the performance of PSAM in fading, interference and noise. In addition to the exact solution, it provides an approximation that is indistinguishable from the exact result but reduces the computation time from days to seconds
