摘要:
针对基于二进制偏移载波(BOC)调制的双支路信号的跟踪问题,提出了基于双环路估计(DET)的鉴相器联合跟踪算法。该算法通过对比BPSK-like、峰跳法、自相关副峰消除技术以及双环路估计算法,选取双环路估计算法来解决BOC调制的跟踪模糊性问题;然后将DET算法应用于双支路上,对双支路的鉴相结果进行线性融合。仿真验证结果表明,基于双环路估计的鉴相器联合跟踪算法能使码跟踪精度在载噪比达到45 dB-Hz的条件下提高到0.06 m。
Abstract:
Aiming at the study of dual-branch signals tracking based on binary offset carrier (BOC) modulation, a joint tracking algorithm of phase discriminator based on double estimation technique(DET) algorithm was proposed. By comparing BPSK-like, “Bump-Jump”, ASPECT and DET algorithm, the algorithm chose DET algorithm to solve the tracking ambiguity problem of BOC modulation. Then the DET algorithm was applied to two-branch, and the phase detection results of two-branch were linearly fused. Simulation results showed that the joint tracking algorithm of phase discriminator based on DET algorithm could improve the code tracking accuracy to 0.06 m when the carrier-to-noise ratio reached 45 dB-Hz.
