This paper studies a cognitive-radio downlink for multiuser covert communications, where a secondary transmitter must serve multiple legitimate users while remaining difficult to detect by a passive warden and operating only within spectrum holes identified by CR sensing. We propose a dual-domain reconfiguration framew...

Pinching-antenna systems (PASS) can reshape an integrated sensing and communication (ISAC) channel through radiating-point placement, but one carrier state generally cannot simultaneously condition a multiuser channel and coherently combine a target echo. This letter studies movable-signal multiple access (MSMA) for th...

Environment division multiple access (EDMA) provides a propagation-centric multiple-access framework for pinching-antenna systems (PASS) by using segmented waveguides and line-of-sight (LoS) blockage to partition the service area and reduce inter-region interference. Recent PASS–movable-signal (MS) studies further sugg...

Improving the energy efficiency of baseband processors has become a critical challenge in mobile communications, especially for energy-constrained edge devices. Applications in conventional baseband signal processors usually adopt independently optimized algorithmic architectures and primarily rely on digital systems,...
