    • PURPOSE: An optical coherent receiver and an optical signal processing method are provided to accurately estimate a frequency, thereby preventing influences of a distorted phase occurring an RZ pulse cover and compensating for the distorted phase. CONSTITUTION: A frequency offset compensating unit(370) estimates a frequency offset about at least one of even samples and odd samples which are inputted from a polarization demultiplexer. The frequency offset compensating unit compensates for the frequency offset of the even samples and odd samples using the estimated frequency offset. A cover distortion compensating unit(390) compensates for distorted phases of the samples whose frequency offsets are compensated for. The distorted phase is generated from a light transferring device.
    • 目的:提供光学相干接收机和光信号处理方法以精确估计频率,从而防止出现RZ脉冲覆盖的失真相位的影响并补偿失真相位。 构成:频率偏移补偿单元(370)估计从偏振解复用器输入的偶数样本和奇数样本中的至少一个的频率偏移。 频率偏移补偿单元使用估计的频率偏移来补偿偶数样本和奇数样本的频率偏移。 覆盖失真补偿单元(390)补偿频率偏移被补偿的样本的失真相位。 失真相位由光传输装置产生。
