Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a cooperative relay network, including a source, a cooperative relay node and a destination node;

[0047] When the information source transmits information to the cooperative relay node, the cooperative relay node collects the energy required in the cooperative communication process from the information broadcast by the information source.

[0048] The cooperative relay node is provided with an energy collection circuit. During the transmission process, the energy collection circuit is activated by an initial energy source, and the energy collection circuit collects energy from the radio frequency signal received through the antenna, wherein the cooperative relay The operating frequency of the node's antenna is the same as the frequency of the received radio frequency signal.

[0049] RF energy signals are received through an antenna, so the antenna must operate at the same frequency as the received signal. In addit...

Embodiment 2

[0062] Such as figure 2 As shown, in this embodiment, a transmission method of a cooperative relay network is provided, and the cooperative relay network has a source, a cooperative relay node, and a destination node;

[0063] When the information source transmits information to the cooperative relay node, the cooperative relay node collects the energy required in the cooperative communication process from the information broadcast by the information source.

[0064] The cooperative relay node is provided with an energy collection circuit. During the transmission process, the energy collection circuit is activated by an initial energy source, and the energy collection circuit collects energy from the radio frequency signal received through the antenna, wherein the cooperative relay The operating frequency of the node's antenna is the same as the frequency of the received radio frequency signal.

[0065] Wherein, as a better implementation of this embodiment: the source and t...

Abstract

The invention provides a cooperative relay network and a transmission method thereof. The cooperative relay network comprises an information source, a cooperative relay node and a destination node, and when the information source transmits the information to the cooperative relay node, the cooperative relay node collects the energy required in the cooperative communication process from the information broadcasted by the information source. According to the invention, the working time of the energy-limited cooperative relay node is prolonged, and the service life is ensured. In addition, an antenna selection scheme is further utilized, the utilization rate of wireless channel resources is increased, and unnecessary waste of the wireless channel resources is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cooperative relay network and a transmission method thereof. Background technique [0002] In order to realize long-distance wireless communication, relay nodes are added in the network to improve the transmission quality. Cooperative relay technology, which is different from traditional multi-hop non-cooperative relay technology, is a new technology that can resist multipath fading of wireless channels. Its basic idea is to allow multiple single-antenna users to share antennas to form virtual multi-antenna cooperative transmission, so that single-antenna users can also obtain space diversity, thereby expanding network coverage, increasing transmission rates and extending battery life. etc. purpose. Cooperative relay protocols in the prior art can be mainly divided into two types, respectively CDF (Cooperative Decode and Forward, cooperative decoding and forwarding) pro...
