摘要
随着导航系统的发展,同时随着信息对抗方法的不断提出,对卫星导航信号同步接收的有效性也提出了新的要求和挑战。针对以长周期/非周期为典型代表的导航信号,提出了一种提高导航信号同步精度的多门限判决法,并对此方法进行了建模与仿真,仿真结果证明,此多门限判决同步法在提高同步精度的同时,大大加快了同步处理速度,从而表明此方法可以有效地提高同步接收的效率。
With the development of navigation system and the methods of information antagonize, the new requirement and challenge are advanced for the synchronization method based on satellite navigation signals. A multi-threshold method of improve synchronization efficiency was proposed and simulated, aiming at the long-period and non-period signals. The result proves that the precision is improved and the rapidity of synchronization is increased by the method, so, the efficiency of synchronization is improved.
