NON-COHERENT DIGITAL APPARATUS FOR RECEIVING IN SPREAD SPECTRUM

摘要

An apparatus for receiving a non-coherent digital signal of a band spread telecommunication mode is disclosed. The apparatus includes an intermediate oscillating unit(302) for generating an intermediate signal; an in-phase converting unit(304) for extracting an in-phase component to provide a digital converted spread signal; a quadrature phase generator(306) for extracting a quadrature phase component to provide another digital converted spread signal; an in-phase early loop(308) for providing an in-phase early signal; a quadrature phase early loop(314) for providing an quadrature early signal; an in-phase punctual loop(310) for generating a punctual signal; an initial synchronizing signal detector(320) for detecting an initial-synchronizing signal; and a synchronizing tracking controller(322) for generating a synchronizing tracking control signal.
