LOWER POWER KU-BAND DIRECT TO HOME VIDEO BROADCASTING IN RAINY REGIONS

The effect of rain on Ku-band satellite broadcasting of analog video s ignals has discouraged the use of Ku-band in many tropical and semitro pical regions of the world. The promise of small home antennas at Ku-b and appeared to be denied in these regions. However, today's new digit al technologies, and recent refinements in CCIR modeling of Ku-band de gradation due to rain, have changed that situation. This paper present s a top level review of how digital technology and rain modeling chang es have improved the viability of direct-to-home Ku-band broadcasting in rainy regions.
