<p><P>PROBLEM TO BE SOLVED: To provide the satellite communications system capable of alleviate interference among different channels, even if the difference in the strength of a received signal is marked among the different channels. <P>SOLUTION: The satellite communications system comprises a means (frequency-generating portion 11 and frequency-converting portion 12), in at least either a transmitting circuit (1) or a receiving circuit. The means is used for allocating the center frequency which is different for each spread code in a spread spectrum communication system. It becomes possible to suppress correlation with other channels, by allocating a different center frequency for each spread code, and thereby, correlation with other channels can be lowered for each spread code. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
