Joint acquisition strategy for BDS B1C signal

  • 摘要: 目前对含有导频通道的新信号的捕获研究,主要是设计联合捕获算法,提高功率利用率以提升接收性能,分为等长与非等长相干积分联合算法两类. 本文针对北斗B1C信号,深入分析了三种等长相干积分联合算法的加权问题,并解释了相干联合与差分联合算法的联系. 理论和仿真结果表明,相干联合算法具有更优的性能;进一步,本文结合最优相干积分时间理论给出捕获参数设计方案,对比了不同场景条件下等长与非等长相干积分联合算法的性能,给出了捕获B1C信号的优化策略.
    Abstract: At present, the research on the acquisition of new signals with pilot channel mainly focused on the design of joint acquisition algorithms, which can increase power utilization so as to improve receiving performance. These algorithms can be divided into two categories: equal length and unequal length coherent integration joint algorithms. For BDS B1C signal, this paper analyzed the weighting problem of three equal length coherent integral joint algorithms, and the relationship between coherent and differential joint algorithm is explained. The theoretical and simulation results show that the coherent joint algorithm has better performance. Furthermore, the design scheme of acquisition parameters is proposed based on the theory of optimal coherent integration time. The performance of the equal and unequal length coherent integration algorithm is compared under different conditions, and the optimal strategy for acquiring B1C signal is given.
