摘要
A data reception apparatus obtains an integrated number of bits by integrating the numbers of bits of a bit string, obtains an integrated number of samples by integrating the number of samples obtained by oversampling each bit, obtains an approximated line that indicates correspondence between the integrated number of bits and the integrated number of samples, determines, based on the approximated line, a bit length of a bit string corresponding to a segment in which identical values continue in oversampling data after the integrated number of samples. Even when a receive-side clock source has a degree of clock frequency error against a transmit-side clock source, how many samples one bit of the bit string corresponds to is obtained with an accuracy higher than a period of oversampling (inverse of the number of samples).
