【 摘 要 】

In this paper we suggest the new approach to modeling RF signals being distorted by the ground propagation environment via impulse response of ground and troposphere channels using the energy delay profile. Representation of the impulse response correlation function using the energy delay profile and the correlation function of impulse response samples is the essense of the approach. While modeling the signal, this representation allows us to take into account the statistical dependence between the impulse response samples (that is a characteristic of short ground propagation traces). The results of output signals modeling are compatible with the experimental results.
