Cross polarization interference
WebDec 13, 2024 · The model shows clearly that the cross-polarization affects only the low-level model but not the top level model. (2) The effect of the cross-polarization on the interference pattern is bidirectional. It will weaken the interference at low satellite elevation angles (∼ 30°) while reinforce the interference at high elevation angles. (3) WebThe present invention relates to a cross polarization interference canceller to be advantageously applied to digital radio communications, more particularly to a cross …
