Sensitivity of OFDM-CDMA systems to carrier frequency offset [PDF]
, 2006 6 pages;This paper presents the impact of a carrier frequency offset on the performance of 2 dimensional spreading OFDM-CDMA systems. This is measured by the degradation of the Signal to Interference plus Noise Ratio (SINR) obtained after despreading and

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.

Iterative Channel Estimation Techniques for Uplink MC-CDMA Systems
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007 In this work, maximum likelihood (ML) channel estimation for uplink multicarrier code-division multiple-access (MC- CDMA) systems is considered in the presence of frequency fading channel. The expectation-maximization (EM)- and a space- alternating generalized expectation-maximization (SAGE) algorithm are introduced to avoid matrix inversion for the ML

Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry
Fish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.
