| 摘 要： | 定位是通过对某一个或几个参数进行估计来实现的，因此参数估计方法是定位问题的关键。卫星干扰源三星定位算法需要测得一对TDOA的值，因此TDOA估计算法是解决问题的关键。本文介绍了经典的基于最小均方误差的自适应时延算法（LMSTDE）原理，并在此基础上加入四阶累积量的概念，改进了LMSTDE在相关高斯噪声背景下不适用的缺点...

| Abstract: | Positioning is accomplished by estimate one or more parameters,so the parameter estimation method is important.The theory of three-satellites location systems is based on the parameter of delay of arrival.We need two TDOA parameters to ascertain the position of interference.The point of this dissertation is TDOA algorithms.It has studied adaptive time delay estimation based on LMSTDE,and improved LMSTDE in related disadvantages of Gaussian noise,and made algorithm for uncorrelated noise usable under low SNR. |
