Embodiment Construction
[0019] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0020] figure 1 It is a diagram of the coding cooperative communication model based on power allocation adopted in the present invention. These include source nodes, relay nodes, and destination nodes. h sr 、h sd and h rd Respectively represent the channel fading coefficient from the source node to the relay node and the destination node, and from the relay node to the destination node. The information sent by the source node is encoded into x 1 and x 2 Two parts, the source node only sends x in it 1 , the relay node sends x 2 . In this system, the transmission rate is set to R=1 / 4b...
