文中提出了扩频接收机捕获模型,并对可行性进行了仿真。在此模型基础上分析了不同干扰样式对接收机捕获性能的影响,给出捕获概率的仿真曲线,对文献[1]、文献[2]中用到的假设的成立条件进行了修正。最后文中采用频域接收机结构并给出了基于频域抑制算法的捕获概率仿真曲线。结果表明捕获性能较之无干扰抑制时大大提高。
In this paper, the acquisition model of spread spectrum receiver is proposed, and the feasibility is simulated. Based on this model, the influence of different interference patterns on the acquisition performance of the receiver is analyzed, and the simulation curve of the acquisition probability is given. The conditions for the establishment of the assumptions used in [1] and [2] are modified. Finally, the structure of frequency domain receiver is adopted and the simulation curve of capture probability based on frequency domain suppression algorithm is given. The results show that the capture performance is greatly improved compared to non-interference suppression.
