Relay processing and power control joint optimization method for two-way relay network

The invention provides a relay processing and power control joint optimization method for a two-way relay network. The relay processing and power control joint optimization method comprises: establishing a two-way relay network model, initializing user transmitting power Pk, establishing a relay processing matrix V of a relay node, updating the user transmitting power based on the relay processing matrix, calculating total transmitting power Ptotal, and repeating the steps, and according to the expression described in the specification, obtaining the optimal transmitting power and the optimal relay processing matrix of a user node. Joint design and optimization of relay processing and power control are achieved, on the condition of meeting a user signal to interference plus noise power ratio, the allocation of the transmitting power of the user node and the relay node is optimized, and the rely node processing matrix is jointly optimized, so that the energy efficiency of a two-way relay network system is optimal.
