The spaced-time correlation function and its effect on the efficient simulation of multicarrier systems
Thaddeus B. Welch · 2003
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.
