Comparison of CP-OFDM and OFDM/OQAM in Doubly Dispersive Channels [PDF]
Future Generation Communication and Networking (FGCN 2007), 2007 In this paper we compare the performance of cyclic prefix based OFDM (CP-OFDM) system and OFDM/offset QAM (OFDM/OQAM) system in doubly dispersive channels, by investigating the signal reconstruction perfectness, time and frequency dispersion robustness, and sensitivity to frequency offset.

New Zealand Journal of Agricultural Research, Volume 69, Issue 3, June 2026.This study aimed to estimate the fractionation of carbohydrates and crude protein (CP), and the ruminal degradation rates of dry matter (DM), CP, and neutral detergent fiber (NDF) in sorghum silages. Silages were prepared with or without the addition of 10% cottonseed cake (CSC, natural matter basis) and Weissella cibaria (W. cibaria).

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication
CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.
