摘要
针对频谱检测技术,对比了三种常见的检测方法,通过建立数学模型和数学分析,提出了一种改进型能量检测法。该方法采用了一种新的平均判决量,相对于经典的能量输出判决量,该平均判决量对ISM 2.4GHz复杂的噪声信号有较强的鲁棒性,最后用MATLAB仿真实验证明了该方法的有效性。
The paper compares three normal spectrum detection technology, by establishing and analysing mathematical model. A new method is proposed to improve energy detection. This method adopts a new average decision value, which has stonger robustness in complex noise signals of ISM 2.4 GHz. Finally, the simulations through MATLAB prove the validity of the proposed method.
