METHOD AND APPARATUS FOR PROCESSING SPREAD SPECTRUM SIGNALS, AND RECEIVER FOR RECEIVING SPREAD SPECTRUM SIGNALS

摘要

This invention provides a method and a device for applying separate integration to realize parallel correlators in frequency-spread communication, in which, a device for processing frequency-spread signals includes an IF signal pre-process unit and multiple parallel separate integrators, the IF signal pre-process unit can generate a pre-integrated result based on the input signal and local reference signals in a preset rate to divide it into multiple groups and each of which includes a pre-integrated result with preset numbers,the multiple parallel separate integrators communicate with said IF signal pre-process unit and each one can receive multiple sets of results continuously and operates the pre-integrated results of the preset numbers of the set relatively with multiple segments of offset false random noise codes so as to get multiple partial relative operation results till to receive the results of preset number of the next group.
