SIGNAL DETECTION FOR SPECTRUM SENSING Spectrum sensing is a critical functionality in cognitive radio communications as it must be performed before allowing unlicensed users to access a vacant licensed band. Energy detector is also known as radiometer and it is most common method of spectrum sensing because of its low computational and implementation complexities. The coherent detector, also referred to as a matched filter, can improve detection performance if the primary transmitted signal, s, is deterministic and known a priori.

通过两个例子，将Optisystem和matlab这两个软件结合进行光学仿真，两个例子分别为光波频率右移和光波幅度调制。通过这两个例子，能很好的理解这两个软件的协同仿真。上传的文件包括文献和源码，还有optisystem的osd文件，文件很全。(Two examples are used to combine the two software Optisystem and MATLAB for optical simulation. The two examples are the right shift of the light frequency and the modulation of the amplitude of the light wave.
