Abstract
A method for processing data in an optical network element. A multi-carrier signal is linear pre-coded and the linear pre-coded signal is modulated. A corresponding optical network element is also described.
Claims11
A method for processing data in an optical network element, the method which comprises:
- receiving a multicarrier signal;
- linear pre-coding the multicarrier signal to form a linear pre-coded signal, wherein each subcarrier is a linear combination of all other subcarriers;
- and
- modulating the linear pre-coded signal by a phase modulation by an amplitude modulation,
- wherein the linear pre-coding of the multicarrier signal is performed using a matrix T,
- wherein the coefficients of a linear combination of a k-th subcarrier correspond to the k-th row of a DFT matrix.

An optical network element comprising:
- a linear pre-coder receiving and precoding a multicarrier signal;
- and
- a modulator configured for phase or amplitude modulation of the linear pre-coded signal multicarrier;
- wherein the linear pre-coder precodes the multicarrier signal matrix T, wherein the coefficients of a linear combination of a k-th subcarrier correspond to a k-th row of a DFT matrix and each subcarrier in the pre-coded multicarrier signal is a linear combination of all other subcarriers.
