摘要:
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.

摘要:
The arrangement includes a transmitter (1-6) with two optical sources (1, 2) generating two optical carrier signals (L1, L2) having different frequencies. The optical carrier signals (L1, L2) are combined and divided in a first coupler (2) and fed to carrier signal inputs of two modulators (4, 5). The mixed carrier signals (L1+jL2, jL1+L2) are separately modulated by two modulation signals (a(t)) and (b(t)) and the modulated signals ((A1+jA2), (jB1+B2)) are combined in a first combiner and emitted as transmission signal (X(t)). Only on demodulator is necessary to regain the modulation signals (a(t), b(t)).
