摘要： When a frequency deviation compensation amount is compensated for by use of frequency shift, a phase offset occurs between adjacent input blocks included in a plurality of input blocks as divided, with the result that an error occurs in a reconstructed bit sequence. A frequency deviation compensation system of the invention is characterized by comprising: a frequency deviation compensation means for compensating for a frequency deviation occurring in a signal by use of frequency shift; and a phase offset compensation means for compensating for a phase offset occurring, in the signal, due to the frequency shift.

摘要： A generation apparatus converts a received key to an encoded key by using an encoding function of an error correcting code, and generates a sketch by applying a first composite transformation on received fuzzy data and the encoded key. A reconstruction apparatus receives a first sketch and a second sketch, generates a composite sketch by applying second composite transformation on the first and second sketches, and reconstruction calculates difference between the two keys used to generate the first and second sketches based on the composite sketch.
