摘要
本文给出一种采用DPT估计SNCK信号时宽—带宽积的方法,并通过仿真该估计方法的性能与其它估计方法进行比较。首先给出SNCK信号参数估计的一般过程。为了便于计算和理论推导,根据估计出的中心频率将接收到的SNCK信号搬移到零频,从而进一步估计其它参数,如采用DPT估计SNCK信号时宽—带宽积。本文将重点研究采用DPT算法估计SNCK信号值的方法。
In this paper, a novel Discrete Phase Transform （DPT）-based method for time-bandwidth product （D） estimation is proposed for Sinusoidal Non-linear Chirp Keying（SNCK） signals. The performance of the proposed estimation method is compared with other methods via simulations. Firstly, a general procedure for SNCK parameter estimation is presented. Then, to facilitate computation and theoretical derivations, the SNCK signal is shifted to zero frequency according to its estimated centre frequency before performing any further parameter estimation, e.g., estimating the time-bandwidth product （D） of SNCK signals using DPT estimation. This paper focuses on the time-bandwidth product （D） of SNCK signals by using the DPT algorithm.
