This paper considers the performance of code division multiple access (CDMA) communications. Of particular interest is the evaluation of the average bit error rate (BER) which cannot be performed analytically in most practical situations. Conventional Monte Carlo simulation can provide an alternative performance evaluation tool. Unfortunately, such an approach is often limited by the excessive computational burden. Importance Sampling is a modified Monte Carlo technique which can significantly reduce the computational cost required to achieve accurate Monte Carlo estimates. In this paper, we will describe the basic principles behind this method. In particular, we will illustrate its use for the efficient simulation of asynchronous direct-sequence (DS) based CDMA systems employing binary phase shift keying modulation along with specific signature sequences for a variety of system parameters.
