Abstract

Fast simulation techniques are applied to estimate error rates of coherent M-ary phase shift keying (PSK) in the presence of co-channel interference (CCI) and additive white Gaussian noise (AWGN). This type of interference occurs often in wireless systems that employ frequency reuse. Error rates are frequently calculated assuming that CCI can be modelled as Gaussian. It is shown that this assumption is valid only in noise dominated environments. Simulation techniques based on adaptive importance sampling (IS) are developed for this problem. Several new numerical results are presented and used to calculate cellular capacities.
