| Abstract: | Fast acquisition for overlapping DS-signals is an important question in developing satellite fast positioning and communication systems. If that technology is feasible, it will not only increase capabilities of multiple access of the system,but also become an indespensable condition of realizing the system. This paper clarifies the source of overlapping DS-signals and the theoretical basis for distinguishing overlapping DS--signals. The hardware realization scheme and part of the measured results are given,and some important conclusions are drawn. |
