信息技术专业 一种MF-TDMA通信体制下的抗干扰技术

一种 MF-TDMA 通信体制下的抗干扰技术摘要分析 MF-TDMA 卫星通信系统，其自身的门限终端就拥有保护时间频率跳变的功能，通过与跳频进行有机结合，从而实现抗干扰的最终目标。本文分析MF- TDMA 卫星通信和自适应跳频技术，归纳并总结二者的特征，对比应用范围比较广的自适应跳频技术，同时，严格按照对比分析的结果，提出保护时间MF- TDMA(AFH- MF- TDMA)卫星通信技术。适应时延 MF- TDMA(AFH- MF- TDMA)卫星通信技术本身是基于分布式干扰检测和频点进行集中规划，拥有干扰检测精准度高的特点外，还拥有频率资源综合利用率高的特征，从而将 MF-TDMA 卫星通信系统的抗干扰能力充分发挥出来。关键词：门限，保护时间，时延，抗干扰Application of Adaptive Frequency-hopping in MF-TDMA Satellite CommunicationAbstract：The MF-TDMA satellite communication system is analyzed, and its own intranet terminal has the function of frequency hopping, and organically combines with frequency hopping to achieve the ultimate goal of anti-interference. This paper analyzes MF-TDMA satellite communication and adaptive frequency hopping technology, summarizes and summarizes the characteristics of the two, compares the widely used adaptive frequency hopping technology, and strictly follows the results of comparative analysis to propose adaptive frequency hopping MF- TDMA (AFH-MF-TDMA) satellite communication technology. The adaptive frequency hopping MF-TDMA (AFH-MF-TDMA) satellite communication technology itself is based on distributed interference detection and frequency point for centralized planning. It has the characteristics of high accuracy of interference detection, and also has the characteristics of high comprehensive utilization of frequency resources. Therefore, the anti-interference ability of the MF-TDMA satellite communication system is fully utilized.Key words: Threshold, Guard time, Delay, Anti-jamming1 引言分析门限适应跳频 MF-TDMA(AFH- MF- TDMA)卫星通信技术，...
