Rain field modelling for fixed microwave radio systems using fade mitigation techniques

Rain field modelling for fixed microwave radio systems using fade mitigation techniques pdf

The demand for increased bandwidth for such services as satellite tv-on-demand has lead to pressure to increase spectrum efficiency and open higher frequencies to commercial exploitation. Fade mitigation techniques such as adaptive transmit power control (ATPC) have been proposed as ways of achieving this. Optimisation of radio systems using these techniques relies heavily on accurate knowledge of the spatio-temporal variation of rain fields. This knowledge is best derived from measured data, but often measurements at the required resolutions are not available. Hence we turn to accurately synthesised rain fields to determine the feasibility and efficient operation of these systems.
