DYNAMIC SPECTRUM SHARING METHOD AND SYSTEM BASED ON CHANNEL STATE REPRESENTATION

摘要

Disclosed is a dynamic spectrum sharing method based on channel state representation. In the method, the channel states of a main system and a secondary system are modeled separately according to service features and scheduling algorithms; a unified model is established for a dynamic spectrum sharing system according to the respective models of the main system and the secondary system; and the communication performance of a secondary user is obtained according to the unified model, and then an access strategy of the secondary user is determined according to the communication performance thereof. Also disclosed is a dynamic spectrum sharing system based on channel state representation. By applying the solution in the present invention, a more realistic condition assumption can be provided for the performance analysis and emulation of the dynamic spectrum sharing system, thus making the performance analysis and emulation of the dynamic spectrum sharing system more accurate, which is advantageous for the dynamic spectrum sharing system to switch the secondary user to a channel with low switching probability in advance, reducing conflicts and switching delay.
