MatLab工程数学应用 非常有用的书 尤其是在数学应用方面(MatLab Application Engineering Mathematics book very useful especially in applications of mathematics)

说明：  简要介绍了认知无线电中基于能量检测的频谱感知方法,在分析能量检测法原理和性能基础上,研究了噪声的不确定性对检测性能的影响. 仿真表明,能量检测法是一种简单、有效的频谱感知方法.(A brief introduction of cognitive radio spectrum sensing based on energy detection method, the analysis and performance of energy detection principle, based on the uncertainty of the noise effect on detection performance. Simulations show that the energy detection method is a simple, effective spectrum sensing method.)
