Abstract: A jones matrix is obtained using coefficients of an equalizer; a parameter of the jones matrix is obtained; a coefficient of an X axis polarization state or a Y axis polarization state in the coefficients is adjusted using the parameter of the jones matrix when the coefficients have singularity characteristics, or energy corresponding to each coefficient of X or Y axis polarization state under each order of a filter in the equalizer is determined using two coefficients of an X or Y axis polarization state in the equalizer coefficients; and a central position of a coefficient tap of X or Y axis polarization state of the equalizer is adjusted using the energy corresponding to each coefficient of X or Y axis polarization state under each order of the filter when the coefficient tap of the X axis or Y axis polarization state of the equalizer deviates from the central position.

Abstract: Disclosed are a multi-lane synchronization method and apparatus. The method includes: forming N data frames, frame headers of the N data frames including an identical frame header sequence, N being greater than or equal to 1 and less than or equal to the number of lanes M, and M being an integer not less than 2; and sending the N data frames via N lanes, wherein different data frames are sent via different lanes, and the frame header sequence is configured to perform frame synchronization between a receiving end and a sending end or to check frame synchronization. Also disclosed are a synchronization system and a computer storage medium.

Abstract: The disclosure discloses a sequence detection method and apparatus, and a computer storage medium. The method includes: acquiring i-path data with the degree of parallelism i; storing x-th i-path data; receiving (x+1)-th i-path data; forming an x-th detection data set by the x-th i-path data and the (x+1)-th i-path data; extracting s paths of data continuously distributed in the detection data set within each of n detection windows to form n data segments; performing a correlation operation between each data segment and a local sequence; and determining, according to a result of the correlation operation, whether a data segment is a target sequence, wherein x is an integer not less than 1, i is an integer not less than 2, n is less than or equal to i, and s is an integer not less than 1 and equal to a bit number of the target sequence.
