Data reproducing apparatus for spread spectrum signal

摘要

The present invention aims to present a data reproducing apparatus for a spread spectrum signal which can synchronize quickly and accurately, using a low cost phase lock loop circuit, in spread spectrum communication. To achieve the object, a peak timing is detected from the output of a correlation circuit for despreading, the output of a correlation circuit exceeding a designated level during a bit rate period near which center the peak timing is put is integrated and data is reproduced according to the polarity of the integrated output signal. Thus, the influence of multi-path fading is reduced, synchronization is not needed in a spread band and TDD synchronization can be held quickly.
