Multiple carrier-frequency offsets (CFO) arise in a distributed antenna system, where data are transmitted simultaneously from multiple antennas. In such systems the received signal contains multiple CFOs due to mismatch between the local oscillators of transmitters and receiver. This results in a time-varying rotation of the data constellation, which needs to be compensated for at the receiver...

Magnetoelectric 0-1 composites comprising CoFe2O4 (CFO) nanoparticles in a polyvinylidene fluoride (PVDF) polymer-fibre matrix have been prepared by electrospinning. The average diameter of the electrospun composite fibres is ∼325 nm, independent of the nanoparticle content, and the amount of the crystalline polar β phase is strongly enhanced when compared to pure PVDF polymer fibres. The piezo...

Joint carrier frequency offset (CFO) and channel estimation is considered for two-way relay networks (TWRNs). Existing estimators provide only the convolved channel parameters and themixed CFO values. In contrast, estimators using a superimposed training strategy are developed for the individual frequency and channel parameters. Depending on the number of pilots, three different estimators are ...

Conclusions: The 6-week intervention led to subjective changes, including a significant decrease in pain. An improvement in symptoms did occur with the 6-week intervention. In addition, dynamic results revealed that custom foot orthoses have an immediate effect on dynamics and that this influence occurs only when orthoses are worn in the footwear. The short-term CFO intervention led to signific...

Carrier frequency offset (CFO) and phase noise (PN) are major oscillator impairments in direct-conversion transceivers, and single-carrier frequency-division-multiple access (SC-FDMA) is the uplink transmission scheme in the longterm evolution (LTE) standard. We derive a new analytical expression for the normalized mean square error (NMSE) in asynchronous SC-FDMA systems under CFO and joint tra...

The Orthogonal Frequency Division Multiplexing-Interleave Division Multiple Access (OFDM-IDMA) scheme, which offers significant improvement on the performance of the conventional IDMAtechnique, has been in the forefront of recent mobile communication researches as it is expected to deliver a high quality, flexible and efficient high data-rate mobile transmission. Most papers on OFDM-IDMA scheme...

We examine how firms evaluate and compensate their chief financial officers (CFOs). CFOs participate in decision making much like other executives, but unlike most other executives they have fiduciary responsibilities for reporting firms’ financial results and safeguarding the integrity of financial reporting. Responsibility for financial reporting raises the question of whether it is appropria...

Evidence suggests that paternal diet can predispose offspring to metabolic dysfunction. Despite this knowledge, little is known regarding the effects of paternal high-fat feeding on offspring insulin sensitivity. The purpose of this study was to investigate for the first time the effects of paternal high-fat feeding on whole-body and skeletal muscle insulin action in young and adult offspring. ...

Residual carrier frequency offset (CFO) and sampling frequency offset (SFO) in orthogonal frequency-division multiplexing (OFDM) transmission result in loss of orthogonality between the subcarriers, which severely degrades system performance. This makes effective CFO and SFO estimation methods essential for such systems. In this work, we address the joint estimation of CFO and SFO, focusing on ...
