A new code acquisition scheme using divided matched filters for a DS/SS signal with frequency offset
M. Mizutani, Takaya Yamazato, Masaaki Katayama, Ami Ogawa · 2002
We discuss the code sequence acquisition of a spread spectrum signal with frequency offset. We propose a method which employs the sets of divided matched filters (MFs) which correspond to partial sequences of the PN code. As the result, it is shown that the proposed method makes the code sequence acquisition possible even with large frequency offset in which the acquisition by conventional methods is impossible.>
