[0043] Further set forth the present invention below in conjunction with accompanying drawing:
[0044] figure 1 It is a system model diagram of the present invention. In cognitive two-way relay networks, we consider the information energy collaboration of a primary system and a secondary system. The primary system consists of two single-antenna primary users, namely primary user 1 and primary user 2, which exchange information with each other. The secondary system consists of a multi-antenna secondary user transmitter and a single-antenna secondary user receiver. The sending end of the secondary user is equipped with N antennas to help the two-way communication between the primary users. The information and energy collaboration process of the entire network is divided into two continuous and equal time slots.
