| Abstract: | This paper presents a method for tracking and demodulation of high dynamic spread spectrum signals. The method simplifies the acquisition and tracking of high dynamic spread spectrum signals by using the digital quadratic loop for carrier acquisition and tracking, simply coherent accumulating and demodulating spread spectrum signals without carrier frequency changes through digital frequency down-conversion, and changing one 2-D into two 1-D acquisition process. |
