Estimating correlation functions for dipoles in correlated Rician-fading scenarios

While the spatial correlation function between two dipoles is well known for Rayleigh fading, that for Rician fading is not available in the literature. Here, a Rician-fading correlation function is proposed for two dipoles separated by a given distance. The existing models for Rayleigh fading are based on the distance between elements. The new idea is to penalize the distance between elements in different ways as the degradation of the environment increases (with increasing Rician -factor). The resulting functions are validated against previously reported results.
