Abstract

The invention discloses a cognitive anti-jamming communication method based on a reinforcement learning algorithm. First, use spectrum sensing to obtain interference-free channels and power, form subsets composed of different frequency channels and transmit power, and mark the index values ​​of each subset, all these subsets constitute a candidate resource set; then, at the initial moment, Each node traverses all subsets, calculates the node's metric value for each subset, and obtains the set of all subset metric values ​​corresponding to the node; again, the node selects a subset corresponding to the maximum metric value from the set of corresponding metric values Set, update the metric value corresponding to the subset; finally, iteratively calculate the metric value within the time range T, and the subset corresponding to the largest metric value can maximize the node throughput. The present invention learns an optimal strategy by using a reinforcement learning algorithm, and each node independently adjusts channel selection and power distribution, so as to maximize the throughput of the anti-interference communication system and achieve the purpose of anti-interference.

Description

technical field [0001] The invention relates to the field of wireless communication, and relates to a communication anti-interference method for improving the capacity of a cognitive wireless network. Background technique [0002] At present, high-density, multi-band deployed wireless communication systems have brought serious electromagnetic interference. Therefore, while pursuing higher speed, longer distance and better service quality, the wireless communication system needs to greatly improve its anti-interference ability. [0003] Generally, spread spectrum anti-jamming and adaptive antenna technology are widely used in communication systems. Spread spectrum anti-interference is usually divided into direct sequence spread spectrum and frequency hopping. The anti-interference principle is to expand the signal spectrum in the frequency domain, thereby reducing the power density of the spectrum, so that useful signals are submerged in interference and environmental noise....
