specific Embodiment approach 1

[0029] Specific implementation mode 1. A spectrum allocation method based on a potential game in a cognitive wireless system, which includes the following steps:

[0030] Step 1: Randomly generate a user channel state table. The horizontal axis of the table represents the channel number of the cognitive user, and the vertical axis represents the cognitive user. According to the state table, the initial assignment of the cognitive user to the channel where it is located;

[0031] Step 2. All users perform Bernoulli experiments. If the user's experimental result is 1, the user will continue to the next experiment as the selected user; if the user's experimental result is 0, the user will continue to stay at this step and wait for the next round of experiments;

[0032] Step 3: The selected user checks the result of the last experiment to see if the result is 1. If the result is 1, the user returns to the previous step, and if the result is 0, proceed to the next step;

Abstract

The invention discloses a latent gaming-based method for distributing frequency spectrums in a cognition wireless system, for improving a frequency spectrum distribution speed in the cognition wireless system, and relates to the technical field of frequency spectrum distribution in a communication system. The method comprises: comparing a user randomly selected by a system and the last gaming user before each gaming begins, and if the two are the same user, commanding the system to reselect another user for this round of gaming, otherwise, performing next round of gaming. Since, repeated gaming of the same user cam not improve a signal-to-interference ratio, in the method provided by the invention, under the condition that system communication quality is ensured, the gaming frequency is reduced so that the system processing speed is enhanced. The provided method is suitable for the frequency spectrum distribution in the cognition wireless system.

Description

technical field [0001] The invention relates to the technical field of frequency spectrum allocation in communication systems. Background technique [0002] Because cognitive users occupy authorized user spectrum resources for communication, once authorized users return to this spectrum space, cognitive users need to perceive and exit the corresponding spectrum space in a short time and choose other spectrum spaces for communication. This requires the spectrum allocation technology to consider ensuring the flexibility of cognitive users to perceive, utilize and withdraw from the spectrum. Secondly, the spectrum allocation technology in cognitive radio must guarantee the communication quality of the system. Due to the limitation of spectrum resources, it is necessary to improve the efficiency of trivial spectrum utilization to ensure system performance. When users use wireless spectrum resources, they will inevitably have different requirements due to their own different ch...
