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

Synthesis, DFT calculations, and investigation of catalytic and biological activities of back‐bond functionalized re‐NHC‐Cu complexes

Applied Organometallic Chemistry, Volume 38, Issue 7, July 2024.
re‐NHC‐Cu complexes have been synthesized and used as catalyst on CuAAC reactions. Five copper complexes (3a–e) stabilized by ring‐expanded back‐bond functionalized N‐heterocyclic carbene ligands (re‐NHCs) were produced in the glovebox by reacting free re‐NHC with CuI precursor.

Reconfigurable Architecture of UFMC Transmitter for 5G and Its FPGA Prototype

IEEE Systems Journal, 2020
[EN] A universal-filtered multicarrier (UFMC) system that is a generalization of filtered orthogonal frequency-division multiplexing (OFDM) and filter-bank-based multicarrier is being considered as a potential candidate for fifth-generation due to its robustness against intercarrier interference as in cyclic-prefix-based OFDM systems.

Intercarrier interference of multiple access UFMC with flexible subcarrier spacings [PDF]

2017 25th European Signal Processing Conference (EUSIPCO), 2017
In this paper we consider multi-user multicarrier transmissions with flexible subcarrier spacings. In a scenario of multiple users access with different subcarrier spacings the orthogonality between subcarriers is disrupted. The paper presents the Intercarrier Interference (ICI) that occurs between two users with different subcarrier spacings in a ...

A Novel Companding-Based Hermitian Symmetry Free ACO-UFMC Scheme for IM/DD in Low-Power IoT-Centric Future Wireless Communications

IEEE Access
For optical communication, the transmitted signal must be real-valued that can be achieved by employing Hermitian symmetry (HS). But the HS results in increased power consumption and decreased spectral efficiency (SE). Therefore, a HS free asymmetrically
