摘要

信道顺序确定和时延估计是参数信道估计的重要内容。本文首先提出了一种基于恒虚警率(CFAR)的多径信道阶数检测方法。然后，在阶数确定后，通过旋转不变性技术(ESPRIT)估计信号参数，进行时延估计。最后，详细分析了时延估计的性能。

Improved channel order determination and its influence on delay estimation

Channel order determination and delay estimation are important contents in parametric channel estimation. In this paper, an improved approach based on constant false alarm rate (CFAR) to detect the order of multipath channel is presented first. Then, delay estimation based on the estimation of signal parameters via rotational invariance techniques (ESPRIT) after order determination is conducted. Finally, the performance of delay estimation is analyzed in detail.
