Abstract

As multicarrier (MC-DS-CDMA) communication systems become more complicated, the utilization of computer simulations to estimate the bit error performance of these systems will increase. Knowledge of the simulated channel´s autocorrelation function can allow for the reuse of the complex channel gains. With the reuse of these complex channel gains, the estimate of a multicarrier system´s performance can be accomplished in less than half the previously required time
