摘要/Abstract

摘要：

针对正弦调频(sinusoidal frequency modulation, SFM)干扰下二进制偏移载波(binary offset carrier, BOC)信号捕获困难的问题,提出了一种基于离散SFM变换(discrete SFM transform, DSFMT)和部分匹配滤波结合全相位快速傅里叶变换(partial matched filter-all phase fast Fourier transform, PMF-apFFT)的干扰抑制捕获改进算法。该算法首先通过FFT估计SFM干扰的调制频率,在调制频率估计的基础上进行DSFMT,然后从DSFMT域中去除干扰成分再做DSFM反变换(inverse DSFMT, IDSFMT)实现干扰抑制,最后对干扰抑制后的BOC信号采用PMF-apFFT方法完成精确捕获。理论分析与仿真结果表明,所提算法在不影响DSFMT性能的前提下大幅简化了传统DSFMT的计算复杂度,并且在同等情况下,当检测概率为1时，所提算法的性能相比于DSFMT结合PMF-FFT的算法提高了大约3 dB。

Abstract:

Aiming at the problem of capture difficult of binary offset carrier (BOC) signal under the sinusoidal frequency modulation (SFM) interference, an improved algorithm of interference suppression capture based on discrete SFM transform (DSFMT) and partial matched filter-all phase fast Fourier transform (PMF-apFFT) is proposed. Firstly, the algorithm estimates the modulation frequency of SFM interference through FFT, and carries out DSFMT based on the estimation of modulation frequency. Then remove interference components from DSFMT domain and do inverse DSFMT (IDSFMT) to realize interference suppression. Finally, the PMF-apFFT method is used to realize the precise capture of the BOC signal after interference suppression. Theoretical analysis and simulation results show that the proposed algorithm greatly simplifies the computational complexity of traditional DSFMT without affecting its performance, and under the same condition, when the detection probability is 1, the performance of the proposed algorithm is about 3 dB higher than that of DSFMT combined with PMF-FFT.

Key words: sinusoidal frequency modulation (SFM) interference, discrete sinusoidal frequency modulation transform (DSFMT), all phase fast Fourier transform (apFFT), binary offset carrier (BOC)
