Abstract

This invention relates to a method for parallel frequency spectrum distribution avoiding interference in a radio system especially to that in CR system including testing usable spectrum resources, computing the gain of users, obtaining an interference matrix by testing the mutual interference, selecting the target rule of the spectrum distribution, computing the gain of the user at the band m and distributing frequency bands, in the total distribution process, all steps to the band M spectrum can be done independently to reduce the cost and shorten the distribution period.

Description

technical field

[0001] A parallel frequency spectrum allocation method for avoiding interference in a cognitive radio (Cognitive Radio) system belongs to the technical field of wireless communication, and in particular relates to frequency spectrum allocation applied in a cognitive radio system. Background technique

[0002] With the continuous expansion of wireless applications, the lack of spectrum resources has become an unavoidable problem in the process of wireless application research. However, from some research results, it can be seen that the lack of spectrum resources is more caused by the unreasonable use of wireless access technologies. of. The existing spectrum allocation methods for different wireless communication systems are mainly based on a fixed allocation method, that is, a certain wireless spectrum block is allocated to a specific wireless access network, and then the wireless spectrum block is divided into several spectrum sub-blocks. The size of the s...
