白噪声的测试MATLAB程序，及各种谱分析(whitenoise test program and Spectrum analysis)

This program tabulates the given function, check out the code for more information. Its in estonian but its not that difficult to understand.

说明：  可以实现2ask的调制，在信噪比SNR为0，10，20。如有需要者可下载。(it is a good matlab program! it can produce a 2ask signal at SNR=0,10,20.)

仿真psk信道的一篇，PDF格式，内有源代码，完美运行，不信可以试试哦(A channel simulation psk, PDF format, the source code, the perfect run, do not believe you can try oh)

EMIRS 利用小微扰法计算二维高斯粗糙面的辐射系数(EMIRS computes the emissivity from 2-D Gaussian dielectric rough surface using small perturbation method (SPM))

通信原理基于MATLAB的计算机仿真，课本上的源代码(Communication Theory MATLAB-based computer simulation, source code on the textbook)

根据目标RCS起伏的特征给出相应的检测概率计算方法。书中常用的办法(According to the characteristics of the fluctuation of the target RCS, the corresponding detection probability calculation method is given. Common methods in books)

Some thing about the communication

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.)
