Digital twin of physical layer carrier data

A method for providing one or more performance characteristics of a physical layer for Discrete Multi-Tone, DMT, based communication, the method comprising:

• receiving one or more first inputs, each first input indicative of a parameter associated with the physical layer;
• receiving one or more second inputs, each second input indicative of a performance characteristic, of the physical layer, to be output;
• selecting, based on the one or more second inputs, one or more processing modules of a digital twin of the physical layer carrier data;
• determining, using the selected one or more processing modules and the one or more first inputs, the one or more performance characteristics;
• and
• providing the one or more performance characteristics as output.

A non-transitory computer-readable medium storing instruction, which when executed by a processor, cause an apparatus including the processor to:

• receive one or more first inputs, each first input indicative of a parameter associated with the physical layer;
• receive one or more second inputs, each second input indicative of a performance characteristic, of the physical layer, to be output;
• select, based on the one or more second inputs, one or more processing modules of a digital twin of the physical layer carrier data;
• determine, using the selected one or more processing modules and the one or more first inputs, the one or more performance characteristics;
• and
• provide the one or more performance characteristics as output.
