In this paper, using discrete event stochastic simulation by batch-means, new results have been obtained by comparing the tele-traffic models commonly used to analyze the capacity of the CDMA system. The traffic capacity of independent M/M/oo cells and homogeneous system of cells are compared. The results indicate that at low blocking probabilities (up to 3% ifshadowing included and up to 5% without shadowing), the two system models have up to 5% difference in traffic capacity while at high blocking probability of 10% there can be as much as 15% difference in the Erlang capacity ofthe CDMA system depending on which model is being used.

“…Since Conway's paper, a variety of methods have been suggested to minimise the effect of the warm-up period and provide results that could be used with a certain confidence. In [24], analysis of results in a cellular environment was discussed. In this paper, the method of the development of a cellular simulation model is further discussed.…”

In this paper, discrete event simulation by batch-means of a M/M/∞ queuing system is utilised to simulate a cellular CDMA system. The details of the simulation model, warm-up period, and simulation run time are discussed. The warm-up period is studied because it affects the accuracy of the results in simulation of communication systems.During the warm-up period-when the simulation system has not reached the steady-state situation-, the system results (eg blocking probability) vary very rapidly from zero to 0.037 for the parameters used. In the batch-means method with 10,000 calls per batch and for 50 batches (500,000 calls), the CDMA blocking probability is 0.0192 with 99% confidence interval.
