Adaptive synchronization enhancement 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 correlated in parallel with segments of the symbol SYNC sequence. Correlation strength estimates of each of the correlated output signals are computed and used to adjust a SYNC threshold level. The correlation strength estimates or the correlated output signals are combined and a peak is determined in the resulting signal. The peak in the resulting signal is compared to the SYNC threshold level to detect synchronization.
