Abstract
Various embodiments provide for data transmission using alert signals to carry data, which can be used in such applications as data network communications between sensors (e.g., cameras, motion, radar, etc.) and computing equipment within vehicles (e.g., smart and autonomous cars).
Claims20
A system comprising:
- a first physical layer device comprising:
- an echo canceller comprising a set of poly-phase filters, the set of poly-phase filters operating based on a set of coefficients;
- a signal output for transmitting an output signal to a second physical layer device;
- and
- a signal input for receiving an input signal transmitted from the second physical layer device, the first physical layer device being configured to communicate data with the second physical layer device over a data transmission medium and to perform operations comprising:
- performing a training operation that adjusts the set of coefficients of the echo canceller, the training operation comprising:
- generating a first set of data-carrying alert signals by modulating a second set of alert signals to carry data;
- transmitting, by the signal output, the first set of data-carrying alert signals to the second physical layer device;
- and
- adjusting the set of coefficients based on the first set of data-carrying alert signals as the first set of data-carrying alert signals is transmitted to the second physical layer device;
- receiving first data to be transmitted to the second physical layer device;
- generating a second set of data-carrying alert signals by modulating a set of alert signals to carry the first data;
- transmitting, as part of the output signal, the second set of data-carrying alert signals to the second physical layer device via the signal output;
- receiving, at the first physical layer device, an input signal transmitted from the second physical layer device;
- and
- generating an echo-cancelled input signal by applying echo cancellation to the input signal using the echo canceller.
