Successive DF relaying: MS-DIS aided interference suppression and three-stage concatenated architecture design

open access: yes, 2012
Conventional single-relay aided two-phase cooperative networks employing coherent detection algorithms incur a significant 50% throughput loss. Furthermore, it is unrealistic to expect that in addition to the task of relaying, the relay-station would ...

Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM

open access: yesApplied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

Insights Into Modulation and Coding Scheme in Mobile Communication

open access: yesDiscrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
With the growing demand for mobile communications and the advancement of technology, reducing energy consumption has become a critical challenge. Overservice, which leads to unnecessary energy waste, is attracting significant attention from both academia and industry. An optimized modulation and coding scheme (MCS) can reduce the energy consumption per

Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

open access: yesJournal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...
