Embodiment Construction

[0060] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.

[0061] Such as figure 2 As shown, the transmission method for increasing the safe reachable rate of an analog network coding two-way relay channel in the present invention includes the steps of: S1: introducing active interference nodes for transmitting interference signals to suppress eavesdroppers from eavesdropping on signals, and legal The receiver can eliminate the influence of the interference signal; S2: In the first time slot, when the legitimate communication node transmits its own signal to the relay node, the interference node broadcasts the interference signal at the same time, which interferes with the eavesdropping of the illegal receiving node; S3 : In the second time slo...

Abstract

The invention discloses a transmission method for improving the safety achievable speed rate of an analog network coding two-way relay channel. The transmission method comprises the following steps that: an active interference node is injected, wherein the active interference node is used for transmitting an interference signal to prevent an eavesdropper from eavesdropping on a signal, and influence of the interference signal on a legal receiver can be eliminated; in a first time slot, when legal communication nodes transmit respective signals to a relay node, the interference node broadcasts the interference signal at the same time to interfere with eavesdropping of an illegal receiving node; and in a second time slot, the relay node amplifies and forwards superposed signals from the communication nodes and the interface node, the communication nodes eliminate two signals according to the known respective signals and the interference signal which is received in the first time slot to obtain the signal of an opposite side, and the eavesdropper cannot eliminate the interference signal completely. The method has the advantage that: by injecting the active coordinated interference node, the aims of preventing the eavesdropper from eavesdropping on the signal and effectively improving the safety achievable speed rate of a system are fulfilled.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method for increasing the safe reachable rate of an analog network coding two-way relay channel. Background technique [0002] In the study of the simulated network coding two-way relay transmission method, the simulated network coding two-way relay eavesdropping channel model contains two legal communication nodes, an amplifying and forwarding relay and a malicious eavesdropper, with A, B, R and E respectively means, such as figure 1 shown. Assuming that there is no direct link between nodes A and B, the simulated network coding is performed through the relay R and the communication is completed by amplification and forwarding; there is a malicious eavesdropper E near node B, and there is no direct link between E and node A. [0003] According to the analog network coding protocol, nodes A and B only need 2 time slots to complete the information exchange....
