Performance Evolution of SC-FDMA for Mobile Communication System
S. B. Lande,Jyoti D. Gawali,S. M. Kharad 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.2
The main aim of this work is to investigate the performance of Single Carrier Frequency Division Multiple Access (SC-FDMA) in mobile communication system. Nowadays there is increase in demand for high speed data transfer in mobile communication. Different multiple access schemes like Orthogonal Frequency Division Multiplexing (OFDM) and SC-FDM are the two important schemes of Long Term Evolution (LTE) for next generation communication. In this paper, we observe the evolution of SC-FDMA in LTE by showing bit error rate variation and PAPR ratio comparison between OFDMA system and SC-OFDMA system.

Mn substituted ZnO nanoparticles with compositional formula Zn_(1-x)Mn_xO where x = 0.00, 0.04 and 0.08were synthesized by sol-gel route. All the samples sintered at 650 ℃ for 12 h in a furnace followed by furnace cooling up to room temperature. X-ray diffraction (XRD) studies shows the presence of hexagonal crystal structure as same as parent compound (ZnO) in all samples. The lattice parameters ‘a’ and ‘c’were determined from XRD data and found that they increase linearly with the Mn content, which suggests that doped Mn ions go to Zn sites. Grain size, X-ray density and Atomic packing fraction (APF)were evaluated using XRD data and found that grain size increases while X-ray density and Atomic packing fraction (APF) decreases with dopant concentration increases. The functional groups and chemical interactions of Mn substituted Zinc oxide samples were also determined at various peaks using FTIR data and observed the presence of function groups in the samples. Results of such an investigation presented in this paper.

The Indium modified mesoporous zeolite AlMCM-41 were synthesized by hydrothermal method and characterized by powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) techniques. The Knoevenagel condensation of aldehyde with malononitrile or ethyl cyanoacetate was carried out at reflux condition in ethanol by using heterogeneous In/AlMCM-41catalyst. This method is fast, efficient, easy work-up and eco-friendly to afford the corresponding Knoevenagel adducts. The catalyst was recovered and reused for several cycles with consistent activity.

Indoxacarb was treated to Plutella xylostella for 10 generations to develop a resistant strain and biochemical analysis of indoxacarb resistance in different tissues of P. xylostella was carried out. Biochemical analysis found maximum esterase activity in gut homogenates of indoxacarb resistant strains followed by whole body and cuticle homogenates. In gut homogenates of indoxacarb resistant strains, maximum increase in esterases was found as compared to the unselected strain. Acetylcholineesterase activity was higher in head homogenates of the resistant strain than in the unselected strain. Glutathione-S-transferase activity was highest in whole body homogenates. However, maximum increase was found in gut homogenates of indoxacarb resistant strains over the unselected. Induced resistance was suppressed using known synergists. Maximum synergism occurred using diethyl-maleate (DEM), followed by triphenyl phosphate (TPP).
