Secure transmission methods and apparatus for low probability of interception in MIMO AF relaying systems.

摘要

The present invention relates to a method and an apparatus for transmitting a multi-antenna amplification and retransmission relay detection signal for secure transmission, the method comprising: receiving a first input signal from a transmitter; The repeater receiving the second input signal from the transmitting terminal through the H channel; And the repeater outputting the first output signal and the second output signal to the receiving end through the G channel and the T channel, wherein the plurality of receiving ends include a legitimate receiving end and an eavesdropping end, , The problem of backward compatibility and the possibility of transmitting multiple data streams
