An iterative frequency-domain decision-feedback receiver for MC-CDMA schemes [PDF]
, 2005 The MC-CDMA techniques (multicarrier code division multiple access) combine a CDMA scheme with OFDM modulation (orthogonal frequency division multiplexing), so as to allow high transmission rates over severely time-dispersive channels without the need of

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.

Adaptivity in MC-CDMA Systems [PDF]
, 2006 This paper investigates the performance of MC-CDMA with link adap- tation in the uplink of a wireless communication system. Two types of link adaptation approaches can be distinguished: 1) Exploitation of channel state information (CSI) at the transmitter and 2) exploitation of CSI at both the transmitter and the receiver.

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.

Self‐Assembly Pathway Influence on Dehydropeptide‐Based Gel Properties and Drug Release
Macromolecular Bioscience, Volume 25, Issue 9, September 2025.In this work, it is explored how the gelation conditions affect the morphology, mechanical properties, and drug release of dehydropeptide‐based gels. The naphthalene‐capped dehydropeptide forms a crystal structure with a pore diameter of ≈4.08 Å. Gelation conditions can influence gel stiffness by nearly three orders of magnitude, in which the assembly ...

CDMA Transmission with Complex OFDM/OQAM
EURASIP Journal on Wireless Communications and Networking, 2007 We propose an alternative to the well-known multicarrier code-division multiple access (MC-CDMA) technique for downlink transmission by replacing the conventional cyclic-prefix orthogonal frequency division multiplexing (OFDM) modulation by an advanced ...
