Abstract
本申请实施例提供一种数据调制方法以及编码器,用于在保留PCTW码型对非线性损伤的抑制效果的基础上,有效提高光传输系统中的线性性能。本申请提供的技术方案如下:编码器对第一组维度和第二组维度进行联合编码得到星座组合点,第一组维度采用双波相位共轭PCTW进行编码,第二组维度采用目标码型进行分区编码,星座组合点之间的最小欧式距离大于多维星座图未进行分区编码的星座点之间的最小欧式距离的倍,多维星座图为基于第一组维度,第二组维度以及联合正交分量I/Q的至少八维星座图;编码器为星座组合点生成映射表;编码器接收携带数字信息的比特序列;编码器将比特序列通过星座组合点的映射表映射为用于传输的符号;编码器将符号发送给数模转换器。
