一种LEO-S频段星地链路传输体制研究
|
摘要
由于低轨卫星系统(LEO)具有传输时延短、传输损耗低等优点,对于实现宽带业务、终端的小型化非常有利;另外,S频段抗雨衰能力强,天线尺寸小造价低,使其很适合卫星移动电话、区域内多用户间数据等业务通信场合。本文针对目前低轨卫星通信需求提出了一种LEO_S频段星地链路传输体制,结合用户数量及传输速率要求,对上下行链路的传输体制进行了研究,计算了上下行链路的余量,并有针对性地提出了星地链路抗干扰措施。
Based on the low transmission delay and transmission loss advantage of the LEO satellite communication systems and high resisting rain loss ability in S-band satellite communications, a transmission scheme for LEO S-band satellite-ground links is proposed in this paper. Under the specific number of users and transmission rate conditions, uplink and downlink transmission scheme and link margin evaluation of the LEO S-band satellite-ground links has been studied, and based on which anti-interference measures for satellite-ground links is proposed accordingly.
