摘要 卫星信号体制是卫星导航系统性能的决定性因素之一,无论是BDS或Galileo等新系统的建设还是GPS或GLONASS等系统的现代化过程中,导航信号的设计与性能评估都是所关注的焦点,BOC调制是GNSS的重要选择,本文引入一种GNSS中有效可调带宽的信号波形以减轻多径和干扰的影响。仿真结果表明:该波形在精度、多径抑制和抗干扰方面较普通BOC具有更好的性能。 Satellite signal structure is one of the most significant factors to decide the performance of GNSS.Focus lies in the designing of navigation signal as well as its performance evaluation no matter under the construction of new systems such as BDS and Galileo or in the development of GPS and GLONASS.BOC modulation is an important choice of GNSS.A new signal wave which is effective to bandwidth adjustment has been brought into this paper to reduce the effects of multipath and interference.The result of simulation shows a better performance in precision,multipath restrain and anti-interference with the new BOC signal wave.
