| 摘要 |
The invention concerns a telecommunications system in which the Earth is divided into areas (26) within which communications are effected by means of transmit and receive means on a spacecraft, such as a satellite, allocated to communication for a plurality of areas. Areas (2610, 2611, 2612) of a first category (28) are allocated signals having respective polarizations (PD, PG) and carrier frequencies (DELTAF1, DELTAF2) such that two adjacent areas of the first category are allocated signals having different polarizations or carrier frequencies. Each area of a second category (30) is allocated signals having all the available polarizations and all the available carrier frequencies. |
