OFDM-IM-Based Spectrum Sharing for Cognitive Radio Networks [PDF]
2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019 In this paper, a novel spectrum sharing scheme, based on orthogonal frequency division multiplexing with index modulation (OFDM-IM), is proposed for cognitive radio networks. In the considered model, the primary transmitter communicates with the primary receiver with the aid of an amplify-and-forward (AF) relay by transmitting OFDM-IM signals ...

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).
