Multi-carrier transmission technology makes full use of frequency and resists multi-address interferences and frequency spreading.So it is frequently used to avoid the equilibrium on the whole bandwidth and overcome the pulse noise influence.In the full paper,we explain in detail the principles of highly accurate multi-carrier positioning systems(see eqs.4 through 7 in the full paper). In this abstract,we just add some pertinent remarks to listing the following two topics of explanation:(1) the establishmen...

现有的定位系统中,2载波定位技术已相当成熟,但在定位精度以及性能方面已经表现出了不足。随着人们对定位精度要求的提高以及GN SS(G lobalN av igation Satellite System)导航定位系统的发展,采用3个载波实现高精度定位的想法在现代GPS和G alileo系统中已被广泛接受。并且已经
