Enhancing Multi-User Detection in Multicarrier 5G and Beyond: A Space-Time Spreading Approach with Parallel Interference Cancellation.

Publication Type: Academic Journal

Source(s): Mathematical Modelling of Engineering Problems. Aug2023, Vol. 10 Issue 4, p1207-1215. 9p.

Abstract: This study explores a composite space-time and frequency-domain spreading strategy, designed to augment the capacity of multicarrier 5G systems operating over frequencyselective Rayleigh fading channels. The focus is directed towards a comprehensive an...

MISO System with Intelligent Reflecting Surface-Assisted Cellular Networks.

Publication Type: Academic Journal

Source(s): Electronics (2079-9292). Jun2023, Vol. 12 Issue 11, p2370. 19p.

Abstract: This paper proposes an architecture based on Intelligent Reflecting Surfaces (IRSs) to improve the performance of future cellular networks. Specifically, we investigate the use of IRSs in combination with statistical Channel State Information (CSI) to ...

Power Control of Reed–Solomon-Coded OFDM Systems in Rayleigh Fading Channels.

Publication Type: Academic Journal

Source(s): Information (2078-2489). Apr2023, Vol. 14 Issue 4, p247. 15p.


Abstract: Power control in an RS-coded orthogonal frequency division multiplex (OFDM) system with error-and-erasure correction decoding in Rayleigh fading channels was investigated. The power of each symbol within a codeword was controlled to reduce the codeword...

Adaptation of Signal with NOMA and Polar Codes to the Rayleigh Channel.

Publication Type: Academic Journal

Source(s): Symmetry (20738994). Oct2022, Vol. 14 Issue 10, pN.PAG-N.PAG. 14p.

Abstract: Polar codes are one of the most effective methods of error correction coding. Currently, these codes are used in 5G communication systems and are the main candidate for 6G. Symmetry plays an important role in coding and decoding algorithms for polar co...

A joint denoising and deep learning detector for OFDM‐IM.

Publication Type: Academic Journal

Source(s): IET Communications (Wiley-Blackwell). Aug2023, Vol. 17 Issue 13, p1513-1523. 11p.

Abstract: Only a subset of subcarriers are activated in orthogonal frequency division multiplexing‐index modulation (OFDM‐IM), which achieves higher energy efficiency and resists frequency offset. In the OFDM‐IM, the energy of the received signal is computed and...


Publication Type: Academic Journal

Source(s): Journal of Engineering Studies & Research. 2022, Vol. 28 Issue 4, p71-77. 7p.

Abstract: This research paper focused on the enhancement improvement of communication system using a combined modulation signal of Quadrature Amplitude Multiplexing and Orthogonal-frequency division multiplexing (OFDM) using a performance metrics of bit error ra...

Energy efficiency analysis and optimization for reconfigurable intelligent surface aided DF relay cooperation with minimum-rate guarantee.

Publication Type: Academic Journal

Source(s): Telecommunication Systems. Aug2023, Vol. 83 Issue 4, p365-380. 16p.

Abstract: We consider an energy-efficient reconfigurable intelligent surface (RIS)-aided decode-and-forward relay cooperation scheme with minimum-rate guarantee. Although the emerging RIS has a similar role as the traditional relay, RIS and relay are essentially...

Outage Performance of Interference Cancellation-Aided Two-Way Relaying Cognitive Network with Primary TAS/SC Communication and Secondary Partial Relay Selection.

Publication Type: Academic Journal

Source(s): Electronics (2079-9292). Nov2022, Vol. 11 Issue 22, p3645. 20p.

Abstract: In this paper, we propose a two-way relaying scheme using digital network coding in an underlay cognitive radio network. In the proposed scheme, the transmit antenna selection and selection techniques are combined using a primary transmitter and a prim...

Performance of cooperative relay protocol in 5G mobile communication network over Rayleigh fading channel.

Publication Type: Academic Journal

Source(s): International Journal of Mobile Communications. 2023, Vol. 21 Issue 4, p494-517. 24p.

Abstract: This paper presents the performance of a new cooperative relay protocol in mobile network over Raleigh environment. Characteristically, the 5G network at 28 GHz covers short distances due to its shorter wavelength. Extending network coverage area and i...
