| 摘要 |
<p>The invention concerns a telecommunication system wherein the earth is divided into zones (26) within which communications are carried out by transmitting and receiving means located in a spacecraft, such as a satellite assigned to communication for a plurality of zones. The system consists in assigning to zones (2610, 2611, 2612) of a first category (28) signals with a state of polarisation (PD, PG) and carrier frequencies (ΔF1, ΔF2) such that for two adjacent zones of this first category are assigned signals with different states of polarisation and carrier frequencies. In each zone of a second category (30) are assigned signals all the available states of polarisation and carrier frequencies.</p> |
