digital correlator meaning in Chinese
数字式相关器
数字相关器
Examples
- To enhance the system reliability , the sample frequency of the digital correlator is four times as much as that of the pn code
为了增加系统工作的可靠性，本系统采用4倍于伪码速率的采样频率。 - The fpga and dsp architecture has been used in the digital correlator , by which the spread spectrum signal can be demodulated at the intermediate frequency
数字相关器采用fpga + dsp的结构设计,实现了扩频信号在中频的解扩解调。 - Eventually , the digital correlator of the modificatory structure is designed and realized by fpga , and it manifests very high and reliable correlative performance
最后用fpga芯片设计并硬件实现了修正结构的数字相关器，这种结构的数字相关器具有很好的工作性能。 - Meanwhile , the influence of doppler effect on pn correlation is analyzed . the realization principle and structure of the digital correlator is analyzed , and then the realization form of the classical and modificatory structure of the correlator is introduced
详细分析了数字相关器的实现原理和实现结构，给出了经典结构和修正结构两种结构的实现形式，分别对两种结构进行了仿真分析，并对不同的实现形式进行了对比。 - Other than traditionally theory analyze and discussion of digital correlator which is laid after demodulator , a scheme based on non - interrelated correlative dll will be discussed in this paper after referencing the theory and the result of simulation . the demodulated data and the information of carrier are not need in this plan . we sample the result of correlation between local sequences and the received signal , then realizing the code synchronization by software
不同于一般的理论分析以及解调后数字相关器的讨论，本文通过理论分析与仿真结果，选用了非相干相关同步的基本结构，并加以改进，不需要解调和载波的信息，将本地序列与接受信号直接相关后进行采样，通过软件的方法，实现同步。
