摘要
并行组合扩频系统相比直接扩频通信传输效率更高,能更好地应用于海上复杂环境无线通信。应用序列代数和的概念,对零相位差处Gold序列良好的代数和相关性进行分析,进一步讨论非零相位差处Gold序列代数和相关的多值特性。针对Gold序列良好的代数和相关特性,并行组合扩频系统在序列非同步情况下建立仿真模型,结果表明Gold序列集可实现并行组合扩频系统的序列自同步。
As compared with direct sequence spread-spectrum communication,parallel combinatory spread spectrum system with high-efficient transmission , has a better application in marine wireless communication. According to the correlation properties of combinatory sequences, the correlation function at zero time delay of eombinatory Gold sequences is analyzed, and the muti-peak value of correlation function at non-zero time delay is discussed. Aiming at the good correlation properties of combinatory Gold sequences, simulation is established in asynchronous parallel combinatory spread spectrum system. The results show that Gold sequences self-synchronization of parallel combinatory spread spectrum system can be realized.
