Abstract :
In addition to the desired signal including direct and diffused components, the received signal is assumed to be contaminated by the Rician-faded interferences of other users within the same cell and the Rayleigh-faded interferences from adjacent cells, as well as the AWGN noise. The path loss is also taken into account. The analysis is based on the statistical distribution of the angle between two complex-valued vectors. An exact distribution of the co-cell interference is derived. Some numerical results of the binary case are presented. Results are compared with those obtained using the Gaussian assumption for the distribution of the interference based on the "law of large numbers"
