Abstract

Disclosed is an MIMO transceiving system applicable to power line transmission, comprising several MIMO transmitters, MIMO receivers, power lines, input terminals and output terminals. In any set, the MIMO transmitter and the MIMO receiver are connected through one input terminal, one power line and one output terminal in sequence; and an operational circuit is arranged between each of the MIMO transmitters and the input terminals, and an operational circuit is arranged between each of the receivers and the output terminals. When the input terminal is connected to the output terminal in normal phase or reversed phrase, the operational circuit conducts addition, subtraction and proportion operations on an input signal sent to the input terminal by the MIMO transmitter or an output signal received from the output terminal by the MIMO receiver, so that the output signal has a linear relation with the input signal. After the technical solution is adopted, no matter how a phase line and a zero line of a power line between terminals are connected, the normal transmission of an input signal between two MIMO devices can be guaranteed.

Description

technical field [0001] The invention relates to the field of signals and systems, in particular to a MIMO transceiver system and communication method using power line transmission. Background technique [0002] As MIMO (Multiple-Input Multiple-Output) technology becomes increasingly sophisticated, more and more devices with MIMO functions are applied in homes, factories, and offices. Since the devices in the above locations all transmit power through the power line, these MIMO devices also need to have the ability to adapt to the power line transmission. [0003] Because in power line transmission, the communication channel is no longer in the radio frequency range, but the wires connecting the wall sockets of various electrical appliances, the channel becomes a bandpass signal, and the MIMO equipment with the original system is not suitable for power line transmission. MIMO devices suitable for power line transmission are thus produced. [0004] However, this type of equi...
