摘要
Abstract
The increasing number of users and their growing demands for service quality have posed significant challenges to 5G communication networks,particularly in handling vast amounts of data with limited spectrum resources.Existing access schemes fail to fully utilize the channel transmission capacity in multi-user communication scenarios.To address this,a Semantic Feature Domain Multiple Access(SFDMA)scheme is proposed.This scheme encodes multi-user information into approximately orthogonal semantic features to support reconstruction-oriented broadcast semantic communication,thereby effectively reducing interference among users.Additionally,a Swin-Transformer-based SFDMA broadcast model is designed,and an SFDMA hardware platform is further developed to validate its performance.Experimental results demonstrate that the proposed SFDMA scheme exhibits superior reconstruction quality and privacy protection in image reconstruction tasks,providing a novel approach for information processing in multi-user interference networks.关键词
