    摘要: An optimization unit(44) in an optical receiver(3) divides a symbol region out of a plurality of symbol regions(C1 to C4) into which signal points that specifies symbol information included in an optical signal are classified, into a plurality of division regions(B1 to B4) from the symbol center coordinate of the symbol region. Moreover, the optimization unit accumulates the signal points of the symbol information for every division region in the symbol region. Furthermore, based on the accumulated number of signal points for every division region, the optimization unit controls the average length of a phase estimation unit(41) when the phase noise of the optical signal is calculated.
