| 中文摘要: |
| 本文提出了一种改进的余弦曲线拟合三点内插时延估计算法，并推导了这一估计算法的方差。在带限高斯白噪声的环境下，考虑多途传播和多卜勒频移的影响，进行了计算机仿真研究。仿真结果与理论分析是一致的。该算法具有较高的时延估计精度。 |
| 英文摘要: |
| An improved time delay estimation algorithm of cosine model three-point insert is proposed, and the variance of the estimation is derived. The algorithm is simulated on condition of band-limited Gauss white noise, multipath propagation, and Doppler frequency shift. The simulation results show a good agreement with the theoretical analysis, and it shows that the algorithm could achieve high estimation precision. |
