The Spread Spectrum integration coherent receiver of the invention employs
a time division multiplexing correlator bank and thus obtained coherent
channel evaluator as a core. The receiver can execute initial PN
synchronization, RAKE diversity coherent combination, AFC and adjacent
cell search and combination receipt, and soft handoff. Further, "part
capture in parallel based on slide energy window" and "tracking loop
based on energy window barycenter" are introduced into the receiver of
the invention, thereby simplifying the structure of the RAKE receiver.
The receiver is capable of overcoming multipath fading, ensuring the RAKE
receipt performance.
