High-order XPD Statistical Properties Assessment for Spectral-efficient Space Ka-band Services

either frequency-reuse schemes or polarization diversity techniques, rely on the joint characterization of the radiowave propagation channel in what concerns the channelinduced interference, by means of the well-known crosspolarization discrimination (XPD), and attenuation. This characterization lacks of assessment by means of a reliable and long-term propagation experimental database, establishing the basis for the future modelling efforts of the depolarization effects, especially at frequency-bands higher than the Ku-band, namely at Ka and above, where the bandwidth required for the deployment of innovative multimedia services is available. In this contribution, the past assumptions taken from limited data collected by experiments at Ku-band are evaluated at Ka-band and the current standard models performance is investigated by means of two testing variables that are now proposed. The evidences found are discussed in-line with the requirements of future modelling efforts.
