Error performance enhancement and complexity reduction in OFDM systems via coordinate interleaving under practical impairments
(Turkiye Klinikleri, 2024)
In this work, subcarrier coordinate interleaving (CI) is implemented to orthogonal frequency division multiplexing (OFDM) systems with the aim of both enhancing the error performance and reducing the implementation complexity. ...
A novel delay-doppler-based channel estimation method in doubly-dispersive ocdm systems
(2024)
Orthogonal chirp division multiplexing (OCDM) has recently emerged as a new candidate for the 6G waveform. In high-mobility wireless channels, the inseparability of the data symbols in both time and frequency domains makes ...
Optimal handover optimization in future mobile heterogeneous network using integrated weighted and fuzzy logic models
(2024)
High mobility travelling trains and drones connected via ultra-dense mobile networks may lead to frequent handovers (HOs). As a consequence, this could arise the mobility problems of the serving network such as handover ...
A novel HARQ design for RSMA networks
(2024)
Rate splitting multiple access (RSMA) has a variety of advantages, including higher throughput, enhanced capacity, and network efficiency, which makes it suitable for beyond fifth generation (5G) networks. Since the combining ...
High range resolution at reduced sampling rates in OFDM systems exploiting pilot aliasing
(2024)
High range resolution (HRR) is critical for automotive radar where it is directly dependent on the available transmission bandwidth. However, HRR sensing for OFDM entails high sampling frequencies, which extends the system's ...
Pairwise sequency index modulation with OTSM for green and robust single-carrier communications
(2024)
In this letter, inspired by the fundamental thoughts of sequency index modulation (SeIM) and orthogonal time sequency multiplexing (OTSM), a novel technique is introduced for green and robust single-carrier communications ...
