English Description：
Since the 1930s, the Federal Communications Commission (FCC) has fraudulently controlled radio spectrum energy. They license specific parts of users in specific geographic areas. Few, small, unlicensed bands are still on and anyone can use them as long as they follow a certain power regulation. These unlicensed bands have become packed with everything from wireless networks to digital cordless phones. To combat overcrowding, the FCC has investigated new ways to manage RF resources. The basic idea is to allow people to use licensed frequency pro to provide them with assurance that interference perception master licensees will be negligible. With the development of software and cognitive radio, the practical way to do this is on the horizon. In 2003, the FCC released a memo commenting on the use of interference temperature models in controlling spectrum. The main goal of this paper is to analyze the feasibility of this mode and develop the media access protocol around it. Second, the implementation of this model system will measure the temperature of current interference TEM before each transmission. Then, it can determine which bandwidth and power it should use to achieve the desired capacity without violating the interference ceiling called interference temperature limit. If the system consists of interference sources, primary licensed users and SEC secondary unauthorized users randomly modeled, we can get some interesting results. In particular, if the impact on the authorized user is healing, the score decreases in the coverage area, and this is held constant, the number of unlicensed nodes through which the secondary capacity user is in direct proportion to the number of nodes is not actually interfered with and transmitted by the primary user. Using the idea of interference temperature multiple access in system analysis, the interference temperature model is developed, analyzed and simulated in physical and data link layer. Overall, the interference temperature model is a feasible method for dynamic spectrum access, and ITMA is a concrete technology to implement it. With the help of cognitive radio, we can reform the spectrum policy and have more room for continuous innovation, ushering in a new era of high-speed personal wireless communication.
