Performance Evaluation of a Novel CDMA Detection Technique: The Two-State Approach
EURASIP Journal on Advances in Signal Processing, 2005 The use of code division multiple access (CDMA) makes third-generation wireless systems interference limited rather than noise limited. The research for new methods to reduce interference and increase efficiency lead us to formulate a signaling method ...

Restoration Ecology, Volume 34, Issue 5, July 2026.Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...
