Considerable non-local electronic correlations in strongly doped Na$_x$CoO$_2$

, 2010
The puzzling electronic correlation effects in the sodium cobaltate system are studied by means of the combination of density functional theory and the rotationally invariant slave boson (RISB) method in a cellular-cluster approach.

BER and PAPR Analysis of UFMC for 5G Communications

Indian Journal of Science and Technology, 2016
Objectives: In this paper, Universal Filter Multi Carrier (UFMC) is recommended for 5G communications and signal scrambling technique is used to reduce Peak to Average Power Ratio (PAPR) in UFMC. Methods/Analysis: UFMC is adequate for 5G communications, but it is also suffers from PAPR as in Orthogonal Frequency Division Multiplexing (OFDM). The signal

Low‐complexity carrier frequency offset estimation for UFMC systems

Electronics Letters, 2019
In this Letter, the authors propose a simple carrier frequency offset estimation for universal filtered multicarrier (UFMC) systems, which not only greatly reduces the computational complexity but also promises excellent performance. First, based on the concept of the bisection method, a low‐complexity selection criterion is designed to iteratively ...
