Abstract :
The characteristics of the signal fluctuations and the channel model are described by several important coherence parameters, which are determined by a two-position, two-frequency and two-time mutual coherence function of the received signals after propagating through random media. The paper discusses these second-order statistical quantities by using an analytic solution to the mutual coherence function for a plane wave recently obtained by iteration of an integral equation. Afterwards, the power impulse response, spectra and delay-Doppler scattering function are also derived and discussed.
