Embodiment Construction
[0044] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0045]As mentioned in the background art, the most obvious manifestation of interference caused by authorized user activities to secondary user communication is the network separation phenomenon in the secondary user network, and this phenomenon is essentially reflected as a change in the topology of the network. Therefore, the spectrum allocation strategy for network topology control can effectively solve this problem and reduce the interference caused by authorized user activities to secondary us...
