This paper derives the outage probability of cognitive radio networks (CRNs) with energy harvesting (EH). The primary nodes have a single antenna, whereas the secondary nodes have multiple antennas. A secondary source S harvests energy from radiofrequency (RF) signal received from primary transmitter PT using nr, S antennas. S also adapts its power so that the interference at primary receiver PR is less than threshold I. The main contribution of the paper is to derive the throughput of multiple input multiple output (MIMO) CRN with RF energy harvesting and adaptive transmit power. We also optimize the secondary throughput by choosing the optimal harvesting duration.

具有能量收集和自适应发射功率的MIMO认知无线电网络的中断概率

本文通过能量收集(EH)得出认知无线电网络(CRN)的中断概率。主要节点具有单个天线,而次要节点具有多个天线。一种二次源š 收获从射频(RF)信号从能量主发射机接收到的P Ť使用Ñ - [R s ^天线。S还调整其功率,以使主接收器P R上的干扰小于阈值I。本文的主要贡献是通过射频能量收集和自适应发射功率来推导多输入多输出(MIMO)CRN的吞吐量。我们还通过选择最佳收获时间来优化次要产量。
