1. A method, comprising:

  • receiving, by a remote unit of a distributed antenna system, one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field, the one or more Ethernet frames associated with a frame repetition rate;

    detecting the start-of-frame field included in a first Ethernet frame of the one or more Ethernet frames;

    extracting a payload of a first Ethernet frame of the one or more Ethernet frames based on the detected start-of-frame field included in the first Ethernet frame;

    determining, after a period of time corresponding to the frame repetition rate, whether an additional start-of-frame field included in an additional Ethernet frame of the one or more Ethernet frames is detected;

    in response to determining that the additional start-of-frame field is not detected, predicting a location of the additional start-of-frame field included in the additional Ethernet frame of the one or more Ethernet frames; and

    extracting an additional payload from the additional Ethernet frame based on the predicted location of the additional start-of-frame field.
