Capture of PN Code Sequence in Spread Spectrum Communication
Zhang Ka · Electronic Science and Technology · 2013
Spread spectrum signal acquisition and tracking is the basis of dispreading positioning spread spectrum receiver. This paper presents an implementation of spread spectrum signal capture and tracking based on FPGA. The design and implementation of the matched filter,carrier tracking loop,and the code tracking loop are given. The parallel capture PN code not coherent spread spectrum communication algorithm is adopted to realize the signal capture by BPSK modulation.
