Synchronization technique for serial modulated waveforms

摘要

Methods and apparatus for synchronization (SYNC) detection of a received serial offset quadrature pulse shaped waveform modulated by a symbol SYNC sequence are provided. The waveform is serially demodulated into a serial baseband signal and serially correlated with segments of the symbol SYNC sequence. Correlation strength estimates of each of the serially correlated output signal are computed and combined to detect a coarse SYNC. The serially correlated output signals are phase corrected based upon phase change conditions and the phase corrected signals are used to detect a fine SYNC.
