Cellular Satellite Systemscell. For example, if the service area is covered by more than one satellite, radio cells are constituted by the illumination areas of the satellite antennas. If a satellite uses spot beams, the satellite footprint is subdivided into radio cells corresponding to the illumination areas of the spot be作者: overture 時(shí)間: 2025-3-22 20:48 作者: 梯田 時(shí)間: 2025-3-22 22:06 作者: EXTOL 時(shí)間: 2025-3-23 02:30

Satellite Orbits, Constellations, and System ConceptsAt this point of the book we present the subject of satellite orbit mechanics to discuss some geometric relations between satellites and ground terminals. We also introduce different satellite constellations which can be used to build up regional or global satellite systems.作者: 魔鬼在游行 時(shí)間: 2025-3-24 14:26
Signal TransmissionThis chapter is not intended to provide a thorough treatment of signal transmission techniques, rather we review the basic concepts of speech coding, modulation, channel coding, and packet transmission schemes as far as they are relevant for the following chapters. For more detailed information thereader is referred to the cited literature.作者: 彈藥 時(shí)間: 2025-3-24 15:47
Multiple AccessA radio communication terminal, satellite, or ground station cannot simultaneously receive and transmit at the same frequency; the transmit signal would heavily jam the receive signal. Therefore, some scheme for separating the forward and return link transmission must be applied.作者: poliosis 時(shí)間: 2025-3-24 21:25 作者: 墻壁 時(shí)間: 2025-3-25 02:12 作者: Immortal 時(shí)間: 2025-3-25 05:50 作者: minimal 時(shí)間: 2025-3-25 11:09
