Analysis on acquisition method in spread spectrum TT&C system

  • In spread spectrum telemetry, tracking and command (TT&C) systems, the integrated baseband equipment has been occupying an important role due to its high flexibility. Limitations of traditional methods were analyzed concerning the complex demands of the integrated baseband equipment. On this basis, a new acquisition method was put forward. The dynamic range of received carrier was divided into sub-intervals, and then dual down-conversions and sectional accumulations were adopted to accommodate larger doppler frequency. The deterioration of acquisition performance in non-coherent modulation systems was solved by a nonlinear transformation as well. Theoretical analyses and simulation results on the proposed method were given, which can provide reference for the design of integrated baseband equipments and for parameter determination in TT&C tasks.
