摘要
伴随着北斗卫星导航系统的发展,新的信号体制应用研究和讨论在快速展开。目前我国已经着手制定新的卫星信号体制,本文分析了BOC(14,2)信号和BPSK-R(1)的特点并分析两种信号的抗干扰性能。重点分析了BOC信号的抗干扰品质因数Q值、J/S值、干扰容限J值和干扰距离等指标,结果表明BOC(14,2)信号比BPSK-R(1)信号的抗干扰能力更强,适合未来北斗系统进行推广使用。
The new signals’applying and researching become popular with the development of BeiDou satellite navigation system.Nowadays the government has the plan to establish the new satellite navigation signals.In this paper,the character and the anti-j amming performance of BPSK-R（1）and BOC（14,2）are analyzed.And the anti-jamming quality factor Q,J/S,In-terference tolerance J and distance of anti-j amming are also calculated.The result shows that BOC（14,2）signals have a better anti-jamming performance than BPSK-R（1）,so the BOC（14, 2）signals are suitable to apply in the future BeiDou satellite navigation system.
