Function for determination of reference signal level (Pref), which is representative of dry weather.

Description

Function for determination of reference signal level, which is representative of dry weather.

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.

The time interval does not have to be an integer but should be equidistant. The minimum time interval length in the time series is automatically computed and is employed as the time interval length.

Usage

RefLevelMinMaxRSL(
  Data,
  Dry = NULL,
  HoursRefLevel = 2.5,
  PeriodHoursRefLevel = 24
)

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. Then every time interval is considered dry and hence used for the reference level determination.
HoursRefLevel	Minimum number of hours that should be dry in preceding PeriodHoursRefLevel hours for computing reference level (h).
PeriodHoursRefLevel	Period over which reference level is to be determined (h).

Value

Reference level (dB).
