Synchronization Acquisition Using Early-Late Gate Based on Frequency-PN Sequence Double Pattern for FFH/BFSK Spread-Spectrum systems

  • 摘要: 针对FFH/BFSK系统的同步难题,该文提出了一种基于频率和PN序列双图案的早迟门同步捕获方法,理论分析和仿真结果显示,该方法门限的选择更为简单、准确;克服了全跳解调时由于收发窗口未同步引起的解调不可靠性。这种捕获方法能进一步提高捕获性能,在信道误比特率为0.1时,同步捕获概率大于95%。分析和仿真结果经过了试验台验证。
