| Summary: | This work investigates fade dynamics of satellite communication systems in equatorial heavy rain region based on a one year of
Ku-band propagation measurement campaign carried out in Universiti Teknologi Malaysia (UTM), Johor, Malaysia. First order
statistics of rain attenuation are deduced and the results are found to be in good agreement with those obtained from other beacon
measurements gathered within the same area (Kuala Lumpur). Moreover, the fade duration and slope statistics of the satellite
signal variations are also carefully derived and subsequently compared with the ITU-R recommendation model. Such information
is useful for the system operator and radio communication engineer for the design of appropriate fade mitigation techniques as
well as the quality of service that could be offered to the user (according to the time interval for a typical day). Further evaluation
on the performances of several ITU-R models in the heavy rain region are needed based on the measurement database available of
this climatic region. |
