| |
| 中文摘要: |
| 本文介绍一种基于余弦函数的相关峰内插算法．在时延估计系统中，为了减少运算量和增加观察时间，采用内插算法是必要的．因为在频率估算时应用了迭代算法，所以无论对于cosx、sinx／x或实际的相关峰，都有相当高的内插精度． |
| 英文摘要: |
| We report the an inner interpolation algorithm of the correlation peak. The in-terpolation is necessary for reducing the sample frequency and increasing the observationtime. We use a Three Point Iteration Method in the frequency estimation, and conse-quently the interpolation method has higher precision for the cos(x) or the sin (x) /x func-tion of the correlation peak, in the time delay estimatiom system. Simulating results aregiven in this paper. |
