Blind Estimation of GPS M-Code Signals under Noncooperative Conditions

Figure 1

BOC-modulated signal waveform BOC-modulated signal waveform. The waveform in the first row represents the data code after spreading. The waveform in the second row represents the subcarrier. The third line of the waveform represents the data code using BOC modulation. These waveforms are rectangular pulses with amplitudes of +1 and −1.
