Abstract
Systems and method of compensating for transmission impairment are disclosed. One such method comprises: receiving an optical signal which has been distorted in the physical domain by an optical transmission channel; and propagating the distorted optical signal backward in the electronic domain in a corresponding virtual optical transmission channel.
Claims20
A method of compensating for transmission impairment, the method comprising:
- receiving an optical signal which has been distorted in the physical domain by an optical transmission channel;
- and
- propagating the distorted optical signal backward in the electronic domain in a corresponding virtual optical transmission channel.
A receiver comprising:
- memory containing instructions stored thereon;
- a processor configured by the instructions;
- an optical detector configured to receive an optical signal which has been distorted in the physical domain by an optical transmission channel and further configured to provide a corresponding distorted electrical signal to the processor,
- wherein the processor is configured by the instructions to:
- propagate the distorted electrical signal backward in the electronic domain in a corresponding virtual optical transmission channel.
