Provided is a correlation scheme selecting apparatus and method that can acquire initial synchronization efficiently by calculating frequency error criterion threshold between correlation schemes and selecting a correlation scheme for each region when a correlation value is calculated for initial sync in a communication system with carrier frequency errors. The method for selecting a correlation scheme based on a carrier frequency error includes: calculating mis-detection probability values based on a normalized frequency offset for each correlation scheme; determining as a frequency-error criterion threshold a crossing point of graphs of the calculated mis-detection probability values for each correlation scheme; and selecting a correlation scheme based on the determined frequency-error criterion threshold.

A method for identifying peptides using tandem mass spectrometry takes the spectrum for a peptide to be analyzed and uses a scoring function to score a match between the spectrum and each candidate peptide in a peptide database. The scoring function has a value corresponding to a number of fragment peaks in the spectrum that match fragment peaks in a spectrum of the candidate peptide. Using the match scores, a generating function of the spectrum is computed to determine the number of peptide reconstructions at each value of the scoring function. The generating function is then used to determine the number of candidate peptides for each match score and the probability of a peptide having a given match score to the spectrum. A spectral probability can be determined by calculating the total probability of all peptides with scores equal to or larger than the given match score.

Provided is a correlation apparatus and method for acquiring a robust synchronization. The correlation method may include: calculating a received symbol phase difference with respect to a received symbol; calculating a correlation SoF symbol phase difference with respect to a correlation SoF symbol for a correlation; calculating a differential correlation value of the received symbol using the received symbol phase difference and the correlation SoF symbol phase difference; calculating a Euclidean distance value of the received symbol using the received symbol phase difference; and calculating a sum correlation value of the received symbol using the differential correlation value and the Euclidean distance value.

Provided is a method for detecting frame sync and frame structure in a satellite broadcasting system. The method for detecting frame sync and frame structure includes the steps of: calculating differential correlation values of reception symbols; generating index sequences of reception symbols whose differential correlation values calculated above exceed a threshold value; calculating positions estimated as frame start points which correspond to a total frame number based on the number of symbols per frame for each frame structure; and detecting frame sync and frame structure based on the umber of positions where the above-calculated frame start point estimated positions and the above-generated index sequences are matched.
