AbstractThe bandspread comprehensive coherent receiver of the present invention has time-division multiplexing correlator set and thus obtained coherent channel estimator set as core parts and combines PN initial sync and tracking, PAKE diversity coherent mergence, AFC and multi-section search and merging receipt and area-crossing soft change-over into one integral. While parallel multipath energy window processing, the partial parallel capture method based on sliding energy window, the tracking loop based on energy window gravity center and other design methods are introduced. Compared with available separate singlepath treatment, the present invention has greater capacity of overcoming multipath fading, can ensure the optimal performance of RAKE receipt and simplify the hardware structure of RAKE receiver.
