New Method of Tracking for Direct Sequence Spread Spectrum Signal with Non-Coherent Data

To solve the problem of tracking for direct sequence spread spectrum signals where data is non-coherent with code, a new method of tracking is presented. Here the bit tracking loop, code tracking loop and carrier tracking loop work simultaneously to complete synchronization of data, code and carrier phase. With non-coherent relation between data and code, signals can be tracked. Validity of the design is verified by simulation results.
