generators to be emploied in the simulation of complex
TLC systems
• ITALSAT data allows test-benching to verify that
certain statistical properties of the simulation products
are verified

principle of the variable coding (code choosen as a function
of the quality of the channel)
• Realization of a simulator of attenuation time series
embodying the properties of space correlation among the
attenuations in the various links
• ITALSAT data, owing to their quantity and quality, allow the
data reuse in various stations while forcing a wanted the

RICONFIGURABLE KA ANTENNA FRONT-END FOR
ACTIVE RAIN FADE COMPENSATION
(introduction given by Dr. Riva)
• Objective of the study is the possibility of realizing a satellite
transmitter (to be embarked on a GEO satellite) whose
antenna can rearrange its directive pattern in order to radiate
more where more is needed owing to bad weather conditions.
• The principle will be applicable both to broadcasting and
TLC systems
• Input data, for the antenna control, will be furnished by
METEOSAT and ECMWF but the effectiveness of the
system will be tested by using ITALSAT data to simulate the
condition of a generic user affected by tropospheric
attenuation

PRINCIPLES FOR THE “EXPORTATION” OF ITALSAT
DATA TO OTHER LOCATIONS WHILE PRESERVING
FIRST- AND SECOND-ORDERS STATISTICS
(Phase 1: data preparation)
• Separation of effects (rain, gaseous absorption,
scintillations etc.)
• Scaling to a different generic location by applying well
known scaling formulae for each cause
• Rigenerate attenuation time series applicable to the
new location

PRINCIPLES FOR THE “EXPORTATION” OF ITALSAT
DATA TO OTHER LOCATIONS WHILE PRESERVING
FIRST- AND SECOND-ORDERS STATISTICS
(Phase 2: data base decomposition)
• The numerous events present in the data bank (10
years) are decomposed in classes each characterized by
a certain value of peak attenuation. Each class is
identified by a well defined, smoothly shapened,
numerical (i.e. non normalized) cumulative distribution
function. This function is considered as composed by a
normalized function times a weight.
• Wanting to emulate the behaviour of another location it
is possible to evaluate a different set of weights
applicable to the new location in question.
• Any statistics (of first and second order) relative to the
location is then derived by the one of Spino d’ Adda
simply reassigning the weights to the partial statistics
derived from each class

PRINCIPLES FOR THE “EXPORTATION” OF ITALSAT
DATA TO OTHER LOCATIONS WHILE PRESERVING
FIRST- AND SECOND-ORDERS STATISTICS
(Phase 3: forcing the spatial corelation)
• The data base is again partitioned into bloks of a fixed
time length (let sey 1 h)
• Statistics of the attenuation in a single period (e.g.
3600 samples picked up at 1 Hz) conditioned to their
average are prepared
• A model giving the spatial decorrelation of the
averages, worked out by Politecnico di Milano and
Fondazione Bordoni, is then applied.
• A generator of random vectors, each composed by a Nplet of averages, is activated. The matrix of the
covariances can be imposed according to the
abovementioned model.
• Once the averages have been attributed, for a given
hour, the time series caracterized by that averages are
run. If the short term variations are uncorrelated, the
only contribution to the correlation is the one of the
averages, which has been forced

MODEL BASED ON METEO FORECAST & METEO RADAR
A. Page, R. Watson, P. Watson (University of Bath)
Approach
Use of numerical weather prediction (NWP) forecast models and weather radars.
Short interval temporal properties to be inserted (typically varying between 1 sec & 15 min)
Generation of maps of attenuation spatial resolution of a few km & temporal resolution of a few sec.
Three underlying assumptions
Short term correlation (< 15 min.) of fading between fixed radio links is statistically independent
Intermediate term correlation (15 min. to a few days) described by movement of weather systems (radars)
Long-term spectral and statistical properties of fading during aggregated events are stationary
On-average spectral and statistical properties of EHF fading
Rain as a multiplicative process
Meteorological input data
Numerical weather prediction model (UK Met. Office Unified Mode) - hourly outputs - grid length 11 km
For higher spatial and temporal resolution : use of C-band rain radar (5 km resolution & 256x256 grid)
Generation of attenuation time-series
Earth stations can be placed at arbitrary locations in the UK

➵ Only variation : occurrence of the various types of events
➢ ITALSAT database of 7 years of rain fading events :
➵ Rain attenuation events collected from several locations in a database
➵ Events Classified in terms of peak attenuation
➢ Methodology :
➵ Proper scaling for frequency, polarization, elevation, rain height etc.
➵ Calculation of attenuation CDF for the required location (objective function).

ITALSAT DATA AS BENCHMARK FOR ADAPTIVE
CODING MODULATION TECHNIQUES FOR KA/Q BANDS
SYSTEMS
• Study on the advantages obtainable from systems using the
principle of the variable coding (code choosen as a function
of the quality of the channel)
• Realization of a simulator of attenuation time series
embodying the properties of space correlation among the
attenuations in the various links
• ITALSAT data, owing to their quantity and quality, allow the
data reuse in various stations while forcing a wanted the

ITALSAT data for testing advanced
adaptive-coding/modulation techniques
in ka/Q Bands
• Testing various performances of
advanced systems such as availability,
QoS, call-blocking probability, trans_
mission delays, interference etc.
requires a tropospheric channel
simulator able to reproduce various
kinds of statistics of the first and
superior order, including the spatial
correlation between attenuations.
• For this purpose, our proposal is the
use of genuine attenuation time series
obtained from ITALSAT, properly
scaled and re-normalized.

ITALSAT data base characteristics
• Location: Spino d’ Adda
• 10 years of propagation data
• Link elevation: ≅ 40°
• 3 frequencies: ≅ 20, 40 and 50 GHz
• Earth station antenna diameter: 5 m

Scaling philosophy principles
the
various
attenuation
• Separate
contributions by means of filtering
• Scale the time series in frequency,
polarization and elevation according to
ITU-R rules (each contribution scales
differently)
• As for the extrapolation to other
locations preserving both the local
climatology and the spatial correlation
use the time-series decomposition
principle (as summarized in the
following)
CEPIT MEETING 2002 - Baveno

olitecnico di Milano
Decomposition in classes characterized by
peak attenuation
• Almost 3000 events identified
• Partition in classes characterized by peak
value,
duration,
and
conditional
distribution
• Determination of the weights of each
class (h/year) for a generic location, also
different from Spino d’ Adda, so as to
reproduce the long term CD which
characterizes the location in question
• Reproduce, with a simulator, any wanted
statistics by using the true ITALSAT
time-series, after recomposing the
attenuation
contributions
suitably
weighted according to the local
climatological behaviour.
