Device for power line communication, method for transmitting signals, and method for receiving signals

摘要

A device for power line communication is provided, including a transmitter adapted to transmit signals on at least two of a plurality of power line transmission paths of a power line network; a sensor adapted to determine one or a plurality of reflection parameters of one of the plurality of power line transmission paths; and a transmission impedance matching unit adapted to match the output impedance of at least two output ports of the device which each couple to one of the plurality of transmission paths to the impedance of the at least two of the power line transmission paths based on the one or the plurality of reflection parameters. Further, a device including a corresponding reception impedance matching unit is provided and corresponding methods for transmitting and receiving signals.

1. A device for power line communication, the device comprising:
a multiple-input-multiple-output (MIMO) transmitter configured to concurrently transmit signals via a first output port coupled to a first power line transmission path and a second output port coupled to a second power line transmission path, the first and second power line transmission paths included in a plurality of power line transmission paths of a power line network; a sensor configured to determine at least one reflection parameter of at least one of the first and second power line transmission paths; and a transmission impedance matching circuit configured to identically match, based on the at least one reflection parameter, a first output impedance of the first output port to a first impedance of the first power line transmission path and a second output impedance of the second output port to a second impedance of the second power line transmission path.
