Abstract

The invention discloses a network coding protocol power distribution method and system based on channel statistical information, and relates to a network coding protocol power distribution method based on channel statistical information. The method comprises the following steps: S11, an information source node sj respectively sending data signals to a relay node r and a target node di, and the relay node r and the target node di receiving the sent data signals; S12, sending a data signal received by the relay node r to a target node di; and S13, the relay node r calculating channel statisticalinformation received from the target node di according to a power algorithm in an orthogonal amplification forwarding protocol, and the relay node r transmitting power of the channel statistical information modulated through network coding and a signal source node. Closed power allocation of channel statistics information (SCK) reduces network overhead compared to instantaneous channel state information (CSI) based power allocation.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a network coding protocol power allocation method and system based on channel statistical information. Background technique [0002] Cooperative communication has been proven to be an effective way to suppress channel fading and extend coverage. The basic idea is to allow multiple nodes to work together to send and receive information. A typical form of cooperative communication can be illustrated by an example of three nodes. The source node s sends data to the destination node d with the help of the relay node d. In the first slot, node s sends a packet to node d. Due to the nature of broadcasting, transmissions from node s are also listened to by relay nodes r. In another slot, node r forwards the intercepted packet to node d. Because d receives two versions via links s→d and s→r→d. [0003] However, in the above system, one data frame transmission needs to...
