Cognitive radio networks (CRNs) represent an adaptive wireless communication paradigm in which unlicensed or secondary users intelligently access underutilised frequency bands without causing harmful ...
Abstract: This research work presents a reinforcement learning (RL)-based algorithm for dynamically modulating schemes in 5G New Radio (NR) downlink transmissions over a Multiple Input Multiple Output ...
Abstract: Cognitive Radio (CR) technology has gained prominence for its ability to facilitate dynamic spectrum access (DSA), enabling opportunistic access to underutilized frequency bands. In the ...
A group of 38 scientists has issued a stark warning about “mirror life” — synthetic organisms built from reversed biological molecules. These microbes could evade the human immune system, spread ...
