Abstract
A communication system includes a first physical-layer (PHY) transceiver and a second PHY transceiver. The first PHY transceiver includes (i) a first transmitter and (ii) a first receiver including a first equalizer. The second PHY transceiver includes (i) a second transmitter and (ii) a second receiver including a second equalizer. The first PHY transceiver and the second PHY transceiver are configured to communicate with one another over a full-duplex link, including training the first equalizer on a second training signal transmitted from the second PHY transceiver, and concurrently training the second equalizer on a first training signal transmitted from the first PHY transceiver.
Claims17
A communication system, comprising:
- a first physical-layer (PHY) transceiver, comprising (i) a first transmitter and (ii) a first receiver comprising a first equalizer;
- and
- a second PHY transceiver, comprising (i) a second transmitter and (ii) a second receiver comprising a second equalizer,
- wherein the first PHY transceiver and the second PHY transceiver are configured to communicate with one another over a full-duplex link, including training the first equalizer on a second training signal transmitted from the second PHY transceiver, and concurrently training the second equalizer on a first training signal transmitted from the first PHY transceiver.
A physical-layer (PHY) transceiver, comprising:
- an interface, configured to connect to a full-duplex link for communicating with a peer PHY transceiver;
- a transmitter;
- a receiver comprising an equalizer;
- an echo canceler;
- and
- a controller, configured to perform one or both of:
- training the equalizer concurrently with training of an equalizer of the peer PHY transceiver;
- and
- training the echo canceler concurrently with training of an echo canceler of the peer PHY transceiver.
9-10. (canceled)
A communication method, comprising:
- transmitting a first training signal from a first physical-layer (PHY) transceiver to a second PHY transceiver over a full-duplex link;
- transmitting a second training signal from the second PHY transceiver to the first PHY transceiver over the full-duplex link;
- and
- training a first equalizer in the first PHY transceiver using the second training signal transmitted from the second PHY transceiver, and concurrently training a second equalizer in the second PHY transceiver using the first training signal transmitted from the first PHY transceiver.
