摘要:

提出了一种无时差限制的窄带跳频同步系统,将跳频同步划分为两种波形:入网波形和通信波形。入网波形采用9个同步频率,其中3个与时间无关;通信波形采用网内校正时间后的高位TOD生成的7个同步频率。收、发电台在任何时差的情况下,即使在70%频点被干扰时,也能保证可靠、有效地完成同步。

关键词: 跳频, 同步系统, 时差, TOD

Abstract:

This paper proposes a narrowband frequency hopping (FH) synchronization system without time difference restriction.FH synchronization will be partitioned into two waveforms: net entry waveform and communication waveform.The net entry waveform adopts 9 synchronization frequencies,of which 3 frequencies are independent of time.The communication waveform adopts 7 synchronization frequencies based on the Time of Day (TOD) after correction of time in the net.However,in the case of any time difference,the transceiver can achieve reliable and efficient synchronization even if 70% bandwidth is interfered.

Key words: frequency hopping;synchronization system;time difference;TOD
