摘要： An orthogonal frequency division multiplexing (OFDM) communication system includes a first interface having a first cable coupler to couple to a first end of a coaxial cable, and a first plurality of signal pathways coupled to the first cable coupler. Each signal pathway of the first plurality includes a physical (PHY) layer component and a radio frequency (RF) front end coupled to the PHY layer component. The system further includes a second interface having a second cable coupler to couple to a second end of a coaxial cable, and a second plurality of signal pathways coupled to the second cable coupler. Each signal pathway of the second plurality corresponds to a signal pathway of the first plurality and includes a PHY layer component and an RF front end coupled to the PHY layer component.

摘要： A carrier tracking technique includes allocating a first number of bits per symbol to a carrier tracking subcarrier of a plurality of subcarriers of an orthogonal frequency division multiplexing (OFDM) signal based on a first target performance margin. The technique includes allocating numbers of bits per symbol to other subcarriers of the plurality of subcarriers based on a second target performance margin.
