ABSTRACT:
A method for determining boundaries of information elements for a PRN code modulated signal is provided. The method of the present invention measures a symbol phase of the received signal and correlation values of different durations to determine the information element boundary. By the method of the present invention, the determination of the information element boundary can be more effective especially in the common dump receiver architecture, wherein a reference wave used in the correlation measurement of the receiver cannot match the received waveform exactly.
