Signal transmission optimization of intelligent metasurface-assisted communication system based on improved DQNN.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
At present, signal transmission in mobile communication is susceptible to multipath effects and interference, causing a decrease in spectral efficiency and an increase in energy consumption. However, existing methods cannot effectively synergistically optimize beamforming and power allocation. To address this issue, this paper constructs an intelligent metasurface-assisted communication system signal transmission optimization model based on I-DQNN. This model uses dual intelligent metasurface-assisted base stations as the communication architecture core, and combines GCNN and QNN to achieve channel estimation and beamforming optimization. This study introduces Squeeze-and-Excitation Networks, gradient constraints, and parameter sharing mechanisms to optimize and improve the model. In practical applications, the error rate, communication energy efficiency, average latency, and system throughput of the research method were 0.11%, 4.45 bit/Hz/J, 3.05 ms, and 1005.95 Mbps. During its operation, the system failure rate remained below 0.17%, and the number of communication interruptions was only 17 times. The proposed model can effectively enhance the stability and energy efficiency of signal transmission in complex channel environments, significantly reduce bit error rates and delays, and achieve efficient utilization of spectrum resources in high-density user scenarios.
