A Matching Game-Based Channel Allocation Method for Full-duplex Cognitive Radio Networks

Abstract

The invention discloses a matching game-based full-duplex cognitive radio network channel allocation method. The matching game-based channel allocation enables non-authorized secondary users participating in sensing to cooperatively sense a plurality of different channels, thereby improving sensing performance , to maximize the throughput of the entire cognitive radio network while protecting authorized primary user data transmission. The present invention uses a matching game method to solve the channel allocation problem of cooperative spectrum sensing under the full-duplex cognitive radio network, realizes the maximum throughput of the cognitive radio network and protects the data transmission of the primary user as much as possible. The present invention considers channel allocation under the background of full-duplex multi-channel, compared with traditional exhaustive search and greedy algorithm, has the advantage of low complexity, and with the increase of the number of secondary users, compared with greedy algorithm, The matching algorithm is closer to the exact solution of exhaustive search.

Description

technical field [0001] The invention relates to the problem of channel allocation in cooperative spectrum sensing under the cognitive radio network of full-duplex technology, in particular to a matching game-based full-duplex cognitive radio network channel allocation method. Background technique [0002] With the rapid development of wireless applications, spectrum becomes a scarce resource. In order to make full use of spectrum resources, the academic community proposes a cognitive radio network, which enables unlicensed secondary users to use the idle spectrum in an opportunistic access manner. In cognitive radio networks, in order to protect the data transmission of the primary user, the secondary user needs to sense the channel to determine whether the channel is idle before accessing the channel. In order to reduce the false detection probability caused by shadowing and path loss, the academic community proposes cooperative spectrum sensing, which allows multiple seco...
