PreprocessingMinMaxRSL: Function for preprocessing of microwave link data.

In overeem11/RAINLINK: Retrieval algorithm for rainfall mapping from microwave links in a cellular communication network.

Function for preprocessing of microwave link data.

Description

Function for preprocessing of microwave link data. This function performs the following tasks:

1. Link data are selected for microwave frequencies within chosen range.

2. Data selection criteria are applied.

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 input microwave link data do not have to be sorted chronologically.

It is strongly advised to use the same unique link identifier (ID) for a link during the entire processed period(s). First of all, time series of sufficient length are needed in order to compute e.g. a reference signal level. Moreover, utilizing the same ID allows for plotting (continuous) time series from the same link.

Usage

PreprocessingMinMaxRSL(
  Data,
  MaxFrequency = Inf,
  MinFrequency = 0,
  verbose = TRUE
)

Arguments

Data	Data frame with microwave link data (use data(Linkdata) to load example data).
MaxFrequency	Maximum allowed microwave frequency of link in output (GHz; default infinite).
MinFrequency	Minimum allowed microwave frequency of link in output (GHz; default 0).

Value

Data frame with microwave link data.
