摘要

为了避免认知无线电对主要用户的干扰，本文研究了一种多频RTS/CTS方案。假设信道存在瑞利衰落和阴影，我们推导了一种基于多频RTS/CTS方案的闭式干扰避免准则。仿真验证了理论公式的正确性。结果表明，基于多频RTS/CTS方案的干扰避免准则能够合理地避免干扰。讨论了传播特性对判据的影响，分析表明主接收机所需的发射功率受传播特性的影响较大。

Statistical analysis of interference avoidance based on multi-frequency RTS/CTS cognitive radio

In order to avoid interference to primary users within cognitive radio, a multi-frequency RTS/CTS scheme is studied in this paper. Assuming that channels suffer from Rayleigh fading and shadowing, we derive a closed-form of interference avoidance criterion based on multi-frequency RTS/CTS scheme. Simulations are carried out to validate the theoretical formulation. Results show that with the interference avoidance criterion based on the multi-frequency RTS/CTS scheme, interference can be rationally avoided. Propagation impacts on the criterion are also discussed and the analysis indicates that the required transmit power of the primary receiver is affected heavily by propagation characteristics.
