This paper analyses the characteristics of the dual circular polarized land mobile satellite MIMO radio channel using measured and modeled channel data. To describe the small scale fading observed in the measured channel, the model makes use of three parameters, which respectively represent the mean LOS, specular reflected and diffuse multipath signals. The model is validated by comparing the CDF plots of the received signal power and eigenvalues with that of the measured channel. Furthermore, the effects of channel correlation on the capacities of equal power allocation MIMO and dual circular polarization multiplexing (DCPM) is investigated. It is found that only the capacity of the LOS-friendly DCPM is negatively affected by a reduction in channel correlation.
