RELAY AND DATA PROTECTION METHOD OF THE WIRELESS CHANNEL USER USING THE RELAY |
摘要 |
Provided are a relay capable of preventing undesired white noise from being additionally amplified and a method for protecting information of a wireless channel user using the relay. The relay includes: a demodulator which receives signals from a transmitting end and a receiving end, decodes the received signals, and removes white noise added to the received signals; a reconstruction unit which applies, to a signal outputted by the demodulator, channel gain between the transmitting end and a relay, channel gain between the transmitting end and the receiving end, and channel gain between the receiving end and a relay to reconstruct a signal to be transmitted; and a modulator which encodes the signal to be transmitted which is reconstructed by the reconstruction unit and sends the encoded signal to the receiving end. Thus, a cooperative relay receives an artificial noise and decodes and reconstructs the artificial noise, thereby preventing an unnecessary additional white noise from being amplified in the relay. |
