Abstract

The invention relates to a base-station forwarding multi-antenna processing method concerning wireless physical layer safety. A multi-antenna uplink receiving matrix and a downlink transmitting pre-coding matrix of a base station are used for reducing the risk of the eavesdropping of private information between a transmitter and a receiver. The method effectively inhibits malicious eavesdropping behaviors of a malicious eavesdropper through increasing number of base station side antennas. In an actual scene, the private information is transmitted through a base station relay, and the base station can obtain the statistical information of an eavesdropping channel in the actual scene, thereby reducing the outage probability of safety transmission between the transmitter and the receiver. The method is simple and practical, is easy to implement, and is good in application prospect.

Description

technical field [0001] The invention relates to a base station forwarding multi-antenna processing method considering wireless physical layer security, and belongs to the technical field of mobile communication. Background technique [0002] At present, wireless physical layer security has gradually attracted the attention of researchers. Due to the broadcast characteristics of wireless signals, malicious eavesdroppers can easily obtain and crack users' private information, thus posing a serious threat to wireless users' information security. As early as the 1970s, scientists at Bell Labs gave the definition of physical layer security capacity, that is, when a sender (Alice) sends private data to a receiver (Bob), there is a malicious eavesdropper ( Eve) trying to receive their private information, under this model, the physical layer secure channel capacity is defined as the maximum secure communication rate of the main communication channel between Alice and Bob, and the ...
