SATELLITE COMMUNICATION SYSTEM FOR RETRIEVING A PLURALITY OF MODULATED SIGNALS HAVING A CONSTANT MODULUS

摘要

The invention relates to a satellite system for retrieving a plurality of modulated source signals having a constant modulus and comprises a plurality of antennas wherein each antenna is configured to receive the plurality of modulated source signals and convert the received plurality of modulated source signals in an antenna signal vector. The satellite system further comprises a combiner configured to combine a plurality of antenna signal vectors into a single signal matrix and a signal separator configured to separate the single signal matrix into a plurality of separated modulated source signals by means of a constant modulus algorithm. The invention further relates to a tracking system and a method for retrieving the plurality of modulated source signals using the satellite system according to the invention.
