摘要
为了提高系统的传输效率,分析和研究了一种将单载波频域均衡(SC-FDE)技术用于低仰角情况下遥感卫星数据传输的系统方案。在频率选择性衰落严重的情况下,SC-FDE技术的复杂度远小于时域均衡并且具有抗多径干扰性能良好的优点,因此已经得到了广泛的研究。文章给出了低仰角下的遥感轨道卫星信道模型,并着重分析了SCFDE技术应用与此系统的可行性。
In order to improve the transmission efficiency of the system, analysis and study on a Single Carrier Frequency Domain Equalization( SC-FDE) technology for the system of remote sensing satellites data transmission in low elevation cases. The complexity of SC-FDE system is far less than the time domain equalization and it has good performance in resisting multi-path effect when the frequency selective fading is serious, so it has been widely researched. The mode of remote sensing satellite channel in low elevation is given in the article, and then analyzes the application of SC-FDE technology in this system.
