摘要
在进行时延和频移联合估计时,计算TDOA(tim e d ifference of arrival)和FDOA(frequency d ifference ofarrival)比较普遍采用的方法是互模糊函数(the cross amb igu ity function),互模糊函数的计算模型有窄带模型和宽带模型之分,分别有不同的算法和估计性能。本文对不同的算法进行了综述,并对各种算法的适用条件和性能作了分析。
A commonly used method of calculating TDOA and FDOA is the CAF (cross ambiguity function) in joint estimation of time delay and frequency offset. Narrowband model and wideband model are calculation models of the CAF. Both of them have different algorithm and estimation performance respectively. In this paper, different algorithms and their application conditions and performance of two models are described and analyzed.
