Abstract: A novel and realizable scheme of three ways serial-parallel combination and pilot-assisted synchronization and acquisition was proposed in order to realize the synchronization and acquisition of the receiver,which was combined by the non-coherent energy detection of receiver system and the search idea of sliding correlation and pilot-assisted of the coherent receiver system. The synchronization clock can be obtained by using the search idea of step-size on the base-band circuit through the first controllable integrator, and the exquisite synchronization and location information were obtained by using synchronization search through the rest controllable integrators. The key module of circuit realization and the definite process of the scheme of synchronization and acquisition were simulated and analyzed, and it was verified to be feasible by analysis of the time-simulation wave.
