Accurate threshold setting for energy detector is important for example in dynamic spectrum
access. This requires accurate statistical distribution models of the observed energy. In this …

In this paper, we address energy detection for M-ary quadrature amplitude modulation
(QAM) signals. In the literature deterministic signal model is widely used and detection …

Complexity required for spectrum sensing has been a critical barrier to implement cognitive
radio systems, especially when multiple channels to be covered. In this paper, we propose a …

该文研究了认知无线电多信道联合感知的数学模型, 并将此模型转换为以认知系统总吞吐率最大
化为目标的带约束优化问题, 进而提出一种基于免疫克隆的多信道联合感知算法 …

多信道联合感知问题由于具有非凸性使得求解困难, 该文首次尝试用确定性全局优化方法对该
问题进行求解. 该问题首先被转化为单调优化问题, 进而提出一种基于单调优化框架的凸松弛 …
