WebCognitive radio has to be an autonomous agent in order to configure itself to dynamic spectrum environment. And, the characteristics of reinforcement learning, a subfield of artificial intelligence in which the agent learns the surrounding operating environment through continuous interaction and takes an optimum decision on the fly, is in ... WebIn cognitive radio (CR), dynamic spectrum access (DSA) can be used for secondary user (SU) to improve its spectrum efficiency under the limited spectrum resources. However, the SU has to consume more energy to sense the state of primary user (PU) before spectrum access. Therefore, high spectrum efficiency and lower energy consumption …
WebApr 19, 2024 · Dynamic spectrum access (DSA) is a promising paradigm to remedy the problem of inefficient spectrum utilization brought upon by the historical command-and-control approach to spectrum allocation. In this article, we investigate the distributed DSA problem for multiusers in a typical multichannel cognitive radio network. WebWith the rapid development of wireless communication technology, the low utilization of spectrum resources and the high demand for spectrum have always been an urgent and paradoxical problem to be resolved. In order to alleviate this conflict, cognitive radio technology has been proposed. In this paper, we propose a new method of distributed …
