Validation results ITU-R P.1623-1¶
This page contains the validation examples for Recommendation ITU-R P.1623-1: Prediction method of fade dynamics on Earth-space paths.
All test cases were extracted from the ITU Validation examples file (rev 5.1).
Functions tested
Function fade_duration_cummulative_probability¶
The table below contains the results of testing function fade_duration_cummulative_probability.
The test cases were extracted from spreadsheet ITURP1623-1_fade_duration_params.csv from the
ITU Validation examples file (rev 5.1).
In addition to the input-arguments, expected result (ITU Validation), and
ITU-Rpy computed result (ITUR-py Result), the absolute and relative errors
are shown. Each test case is color-coded depending on the magnitude of the
errors (green = pass, errors are negligible, red = fail, relative error is
above 0.01%).
In addition, the code snippet below shows an example of how to generate the first row of the results in the table:
import itur
# Define input attributes

A = 12.51 # (dB)
el = 20.33 # (°)
f = 30.0 # (GHz)
# Make call to test-function fade_duration_cummulative_probability
itur_val = itur.models.itu1623.fade_duration_cummulative_probability(D=D, A=A, el=el, f=f)
# Compute error with respect to value in ITU example file
ITU_example_val = 0.923603873 #
error = ITU_example_val - itur_val.value
error_rel = error / ITU_example_val * 100 # (%)

Function fade_duration_probability¶
The table below contains the results of testing function fade_duration_probability.
The test cases were extracted from spreadsheet ITURP1623-1_fade_duration_params.csv from the
ITU Validation examples file (rev 5.1).
In addition to the input-arguments, expected result (ITU Validation), and
ITU-Rpy computed result (ITUR-py Result), the absolute and relative errors
are shown. Each test case is color-coded depending on the magnitude of the
errors (green = pass, errors are negligible, red = fail, relative error is
above 0.01%).
In addition, the code snippet below shows an example of how to generate the first row of the results in the table:
import itur
# Define input attributes
D = 30.0 # (s)
A = 12.51 # (dB)
el = 20.33 # (°)
f = 30.0 # (GHz)
# Make call to test-function fade_duration_probability
itur_val = itur.models.itu1623.fade_duration_probability(D=D, A=A, el=el, f=f)
# Compute error with respect to value in ITU example file
ITU_example_val = 0.183841589 #
error = ITU_example_val - itur_val.value
error_rel = error / ITU_example_val * 100 # (%)
