5G Channel Estimation Based on Whale Optimization Algorithm
Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023 This paper presents a novel approach, based on the whale optimization algorithm (WOA), for channel estimation in wireless communication systems. The proposed method provides a means to accurately estimate the wireless channel, while not requiring the statistical characteristics of the channel.

Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 Nowadays, multicarrier modulation schemes are being widely used in wireless communication system than single‐carrier modulation techniques. Single‐carrier modulation schemes are less capable of dealing with multipath fading channels than multicarrier modulation schemes, which results in lower spectral efficiency.

IET Optoelectronics, Volume 16, Issue 5, Page 207-217, October 2022., 2022 Abstract Visible light communication (VLC) has emerged as a good accompaniment to radio‐frequency (RF) technologies by deploying multicarrier schemes such as orthogonal frequency division multiplexing (OFDM). However, the coherent summation of carriers in the OFDM system leads to a high peak‐to‐average‐power ratio (PAPR), causing non‐linear clipping ...

PAPR Reduction in UFMC for 5G Cellular Systems [PDF]
Electronics, 2020 Universal filtered multi-carrier (UFMC) is a potential multi-carrier system for future cellular networks. UFMC provides low latency, frequency offset robustness, and reduced out-of-band (OOB) emission that results in better spectral efficiency. However, UFMC suffers from the problem of high peak-to-average power ratio (PAPR), which might impact the ...

Mobile Information Systems, Volume 2021, Issue 1, 2021., 2021 The 3rd Generation Partnership Project (3GPP) adopted cyclic prefix OFDM (CP‐OFDM) for both uplink and downlink communications (although DFT‐s‐OFDM is also allowed in the uplink) in 5G New Radio (NR) Release 15. However, due to the variety of proposed deployment options and scenarios, a single numerology will not be enough to fulfil all performance ...
