Function for correcting minimum and maximum received signal powers.

Description

Function for correcting minimum (Pmin) and maximum (Pmax) received signal powers. For a rainy time interval the corrected minimum received signal power becomes equal to the minimum received signal power if this is below the reference signal level (Pref). Otherwise the corrected minimum received signal power becomes equal to the reference signal level. The corrected maximum received signal power becomes equal to the maximum received signal power if both the maximum received signal power and the corrected minimum received signal power are below the reference signal level.

Works for a sampling strategy where minimum and maximum received signal powers are provided, and the transmitted power levels are constant.

Also works for a sampling strategy where instantaneous transmitted and received signal levels are obtained. In case of instantaneous signal levels, it does not matter whether transmitted power levels vary or are constant. The only requirement is that the input data for RAINLINK needs some preprocessing. See ”ManualRAINLINK.pdf” for instructions.

Also works for a sampling strategy where average transmitted and received signal levels are obtained. In case of average signal levels, it does not matter whether transmitted power levels vary or are constant. The only requirement is that the input data for RAINLINK needs some preprocessing. See ”ManualRAINLINK.pdf” for instructions.

Usage

CorrectMinMaxRSL(Data = DataOutlierFiltered, Dry = NULL, Pref = Pref)

Arguments

Data	Data frame with microwave link data.
Dry	Data frame: Should interval be considered dry for reference level determination? (0 = wet; 1 = dry). Use Dry=NULL if no wet-dry classification has been performed.
Pref	Reference level (dB).

Value

Data frame with corrected minimum and maximum received powers (dB).
