This paper optimizes the throughput of cooperative cognitive radio networks (CRN). There are multiple branches and multiple hops. Transmission is performed on the branch with the highest signal to interference plus noise ratio (SINR). Secondary source and relays have multiple receiving antennas to harvest energy from radio frequency (RF) signal received from primary transmitter P_T. These secondary nodes have multiple transmitting antennas and transmission is performed from the best antenna. Also, secondary source and relays adapt their power to generate interference at Primary Receiver P_R less than a given threshold I. We optimize harvesting duration to enhance the throughput in the secondary network.

本文优化了协作认知无线电网络（CRN）的吞吐量。有多个分支和多个跃点。在具有最高信干噪比 (SINR) 的分支上执行传输。辅助源和继电器具有多个接收天线，以从主发射机接收的射频（RF）信号的收获能量P _Ť。这些辅助节点有多个发射天线，从最好的天线进行发射。此外，辅助源和中继调整其功率以在主接收器P _R处产生小于给定阈值I 的干扰。我们优化收获持续时间以提高二级网络的吞吐量。
