【摘要】：船載衛(wèi)星通信技術(shù)憑借其自身優(yōu)勢,在海洋移動(dòng)通信、軍事偵察、災(zāi)難救援等領(lǐng)域發(fā)揮著重要作用。近年來,隨著網(wǎng)絡(luò)技術(shù)的發(fā)展,船載衛(wèi)星通信系統(tǒng)如何滿足人們對數(shù)據(jù)傳輸和高帶寬等的需求,成為行業(yè)研究熱點(diǎn)。多波束切換技術(shù)能夠?qū)崿F(xiàn)衛(wèi)星頻率的復(fù)用,提高衛(wèi)星信道的利用率,保障衛(wèi)星通信的帶寬質(zhì)量。本文設(shè)計(jì)實(shí)現(xiàn)基于概率估計(jì)的多波束切換算法,該算法能夠避免波束過早切換,緩解波束切換過程中產(chǎn)生的"乒乓切換"問題。
[Abstract]:Shipborne satellite communication technology plays an important role in marine mobile communication, military reconnaissance, disaster rescue and so on. In recent years, with the development of network technology, how to meet the needs of shipborne satellite communication system for data transmission and high bandwidth has become a hot spot in the industry. Multi-beam switching technology can realize the multiplexing of satellite frequency, improve the utilization of satellite channel, and guarantee the bandwidth quality of satellite communication. A multi-beam switching algorithm based on probability estimation is designed and implemented in this paper. The algorithm can avoid premature beam switching and alleviate the problem of "ping-pong switching" in the process of beam-switching.
