摘要:
现代化的GPS和Galileo系统在L1/E1频点增加使用MBOC调制的民用信号。MBOC调制相比BOC(1,1)增加了BOC(6,1)分量,增加高频分量可以提高信号的伪码测量精度和多径抑制性能,但同时也提高了信号捕获的复杂度。文中介绍了MBOC信号3种常用的捕获算法,并从硬件资源和检测性能两方面比较其性能,结果表明窄带匹配滤波捕获算法以损失部分能量为代价,极大降低了实现复杂度。
Abstract:
Modernized GPS and Galileo broadcasts a new multiplexed binary offset carrier (MBOC) modulated civil signal on L1/E1 band. Comparing with BOC(1,1) modulation, extra BOC(6,1) component is added in MBOC signals. The power increase in higher frequency brings more advantage in code tracking accuracy and multipath mitigation; however, it will also cause more complexity in signal acquisition. Three acquisition algorithms for MBOC signals are introduced in this paper, and hardware resource and detection performance of these algorithms are compared. The results show that the narrow band filter matching acquisition algorithm greatly reduces the implementation complexity at the cost of little power loss. In the end, simulation results verify the results.
