| Abstract: | When there is Line-of-sight weight in the mobile communication channel with lots of scatter weights, the statistic model of Rice theory could be used to replace the channel that would be studied, This paper discusses several common methods that were used to simulate Rice channel in computer. Then their performance was compared and the doubts in some method were analyzed in both theory and simulation. And the conclusions that the simulation of Rice fading channels needs colored Gaussian noise processes with shape of certain power spectrum are given. |
| Keywords: | Rice fading simulation probability density function colored Gaussian noise processes |
