Securing Machine‐Type Communications: A Survey on Privacy Threats and Countermeasures
IET Information Security, Volume 2026, Issue 1, 2026.Machine‐type communication (MTC) is a fundamental enabler of the Internet of Things (IoT) and emerging 5G/6G networks, supporting massive deployments of heterogeneous and resource‐constrained devices. However, large‐scale data collection, persistent connectivity, and limited device capabilities introduce critical privacy challenges that are not ...

Demodulating Subsampled Direct Sequence Spread Spectrum Signals using Compressive Signal Processing [PDF]
, 2012 We show that to lower the sampling rate in a spread spectrum communication system using Direct Sequence Spread Spectrum (DSSS), compressive signal processing can be applied to demodulate the received signal.

Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver
Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.

CNS Neuroscience &Therapeutics, Volume 31, Issue 11, November 2025.This work elucidates acupuncture's multisystem therapeutic mechanisms through central‐peripheral crosstalk. Using functional gastrointestinal disorders, psychiatric disorders, and chronic pain models, we demonstrate its efficacy in rebalancing gut‐brain signaling, neuroimmune‐endocrine integration, and humoral network modulation.
