摘要

本文提出了两种最大吞吐量和符号正确率(SCR)的最优资源分配方案。推导了吞吐量和可控硅比。推导出的吞吐量和可控硅分别对传感时间、源发射功率和中继发射功率进行了优化。数值结果表明，最优感知时间依赖于主用户的信噪比。它们还表明，可控硅随继电器数量的增加而增加。

Resource allocation for relay assisted cognitive radio networks

In this paper, we present two optimal resource allocation schemes that maximize throughput and symbol correct rate (SCR). The throughput and SCR are derived. The derived throughput and SCR are optimized with respect to the sensing time, the source transmission power and the relay transmission power. Numerical results show that the optimal sensing time is dependent on the primary user's signal-to-noise-ratio (SNR). They also show that SCR increases with increase in the number of relays.
