Procurement excellence is increasingly becoming an important factor in delivering efficient operations within successful companies. On the surface, effectively measuring procurement performance is no rocket science. However looking deeper, adequate measurement of procurement success is a big issue, as bottom-up reported savings can significantly deviate from the key financial figures a CFO look...

Frequency synchronization is a critical requirement for single-carrier frequency division multiple-access (SC-FDMA) uplink transmissions. Based on the key observation that the received signal at the base station can be formulated as the parallel factor analysis model, we present a joint carrier frequency offset (CFO) estimation and compensation scheme for SC-FDMA uplink transmissions with inter...

In this paper, we present a real-time implementation of 2×1 MIMO system using the Alamouti scheme. The real-time chain is based on the LTE parameters. The testbed is implemented using FieldProgrammable Gate Array (FPGAs) through Xilinx System Generator for DSP. Time-domain synchronization is achieved through a joint maximum likelihood (ML) symbol-time and carrier frequency offset (CFO) estimato...

Carbon fluoroxide (CFO) nanoparticles (NPs) produced from silicon carbide wafers are used as both fluorescent probes and sonosensitizers for theranostic application. In vitro cell tests were carried out to investigate the feasibility of ultrasound-based therapy with the use of the CFO NPs. The NPs that penetrated inside the cells were shown to provoke cell destruction after application of an ul...

Orthogonal frequency division multiplexing system is multichannel system that provides high rate and high quality wireless communication services, but system performance is degraded by two factors, one is the symbol timing offset (STO) and other is the carrier frequency offset (CFO) caused by Doppler frequency shift. Several approaches have been proposed to estimate time and frequency offset. M...

Electrical control of magnetization or magnetic polarization offers an extra degree freedom in materials possessing both electric and dipole moments, viz., magnetoelectric (ME) multiferroics. A microstructure with polycrystalline configurations that enhances the overall polarization/magnetization outperforms single crystalline is identified a 1–3 CoFe[Formula: see text]O[Formula: text]–BaTiO[Fo...

Orthogonal frequency division multiplexing (OFDM) systems are known to be sensitive to carrier frequency offset (CFO). This paper is concerned with the CFO estimation for multiple input multiple output (MIMO)systemsemployingOFDMwaveforms. We present two approaches to derive maximum likelihood (ML) pilot-assisted frequency estimators that use either two or multiple identical training symbols. It...

A new method for frequency synchronization based upon Zero-Intermediate Frequency (Zero-IF) receiver and characteristics of the received signal’s power spectrum for MC-DSCDMA-Uplink system is proposed in this paper. In addition to this, employing Zero Correlation Zone (ZCZ) sequences, designed specifically for quasisynchronous uplink transmissions, is proposed to exploit frequency and temporal ...
