In this paper, we suggest a new transmission technique for cognitive radio networks. The proposed adaptive underlay/interweave transmission technique is evaluated in the presence and absence of primary interference. The proposed adaptive underlay/interweave transmission technique offers 1–3 dB gains with respect to conventional cognitive radio networks (CRN) using either underlay or interweave. The proposed protocol is extended to CRN with energy harvesting using radio frequency (RF) signals. Our results are valid for any position of primary and secondary transmitter and receiver.

用于认知无线电网络的自适应底层/交织传输协议

在本文中，我们为认知无线电网络提出了一种新的传输技术。在存在和不存在主要干扰的情况下评估所提出的自适应底层/交织传输技术。与使用底层或交织的传统认知无线电网络 (CRN) 相比，提议的自适应底层/交织传输技术提供 1–3 dB 的增益。提议的协议扩展到 CRN，使用射频 (RF) 信号进行能量收集。我们的结果适用于主要和次要发射器和接收器的任何位置。
