摘要:

在以往的认知无线电研究过程中,研究者通常忽略了传播信道的随机性和授权用户位置的不确定性对频谱感知的影响。本文提出了基于概率模型的动态频谱使用策略,并分析研究了支持向量机在频谱接入准则设计中的应用。

Abstract:

The challenges posed by the randomicities of radio channels and uncertainties of primary user’s location were first analyzed in spectrum sensing issue.A dynamic spectrum access strategy based on probability model was proposed in this paper.The implementation of SVM to spectrum sensing was discussed and designed.

Key words: cognitive radio, spectrum sensing, support vector machine
