| 摘 要： | 摘要：跳频OFDM通信系统具有抗干扰和抗多径衰落的能力，能够大幅提高无线通信系统的信道容量和传输效率。同步技术是FH-OFDM系统关键技术，其性能直接影响到FH-OFDM系统可靠性和鲁棒性。将基于扫描的跳频同步方法与OFDM同步技术结合在一起，完成跳频OFDM系统同步。研究表明，这种算法具有很好的工程参考价值，且当多个频点被干扰时，系统正确同步概率和OFDM符号正确同步概率性能较好。 |

| Abstract: | :FH-OFDM can not only effectively enhance the transmission rate and capacity of the wireless of communication system, but also effectively combat multi-path fading and interference. Synchronization was one of the key technologies of the FH-OFDM system, its performance will affect the reliability of the system. This article combined the algorithm of FH synchronization based on frequency scanning with the algorithms of OFDM synchronization to finish the synchronization of the FH-OFDM system. The simulation results show the correct synchronization probability of system and correct timing probability OFDM. The research indicates that it is of great reference value for engineering realization. |
