Claim Text:
1. A method of tap coefficient correction, comprising: obtaining a synchronization symbol difference between a first polarization and a second polarization orthogonal to the first polarization; calculating a tap coefficient gravity center of the first polarization and a tap coefficient gravity center of the second polarization based on a total sum of power in all tap numbers of a corresponding finite impulse response filter and a square of power of individual tap numbers of individual sequence, the tap coefficient gravity center of the first polarization and the tap coefficient gravity center second polarization represent a delay amount of each of the first polarization and the second polarization in an adaptive equalizer respectively; calculating, based on the synchronization symbol difference and the delay amount of each of the first polarization and the second polarization, a correction reference gravity center of the tap coefficients set in the adaptive equalizer where a tap position number is set as a gravity center of tap coefficients, the tap coefficients corresponding to taps included in the adaptive equalizer; and performing a correction by shifting the tap coefficients to cause the correction reference gravity center to be closest to a tap center.
