| Abstract: | The cognit intelligent spectrum sharin of spectrum sharing, and tel spectrum sensing, spectrum management is analyzed. The IV g ls e radio has the ability for dynamically reusing the idle spectrum resources. An system could improve the efficiency of spectrum usage. This paper gives the process of indetail the function and recent research on the relatedtechnologies, including allocation, spectrum access and spectrum mobility. The key technology of spectrum spectrum pooling strategy, spectrum allocation algorithm and power control are alsopresented emphatically. |
