“…It is clearly observed from Fig. 4a that the ABER performance of GASM is better than other standard MCSs [13]- [15], especially in the practical SNR range. For example, at fixed SNR = 30 dB, the ABER of GASM, OFDM, FrFT-based OFDM, GFDM, and OCDM are 5.35 × 10 −4 , 4.05 × 10 −3 , 1.24 × 10 −3 , 1.04 × 10 −3 and 5.21 × 10 −3 respectively.…”

This study aims to present a comparative analysis of existing waveforms for Integrated sensing and communication (ISAC) in vehicular environments. Further, a novel multicarrier framework based on Generalized Adaptive Spreading Modulation (GASM) is proposed for ISAC-enabled vehicular environments. The GASM waveform offers symbol spreading in both time and frequency domains with tunable spreading parameters, which allows the proposed GASM-based waveform to adapt according to the rapid time-frequency variations of the fading channel and combat the most common system impairments such as carrier frequency offset (CFO) and symbol timing offset (STO). The GASM scheme is the generalization of various existing waveforms such as Orthogonal frequencydivision multiplexing (OFDM), Fractional Fourier Transform based OFDM (FrFT-based OFDM), and Orthogonal Chirp Division Multiplexing (OCDM). The proposed GASM-based ISAC system is evaluated in terms of average bit error rate (ABER) for communication and ambiguity function (AF) for range and Doppler capabilities. The performance of GASMbased ISAC system is compared with existing waveforms, i.e., OFDM, FrFT-based OFDM, OCDM, Generalized Frequency Division Multiplexing (GFDM), and Orthogonal Time Frequency Space (OTFS) modulation. It is observed from the simulation results that the proposed GASM scheme outperforms all existing waveforms due to its superior competence in handling fading and synchronization errors. I.

Unmanned aerial vehicles (UAVs) are becoming increasingly popular in various industries, including telecommunications. In the realm of 5G new radio vehicle‐to‐everything (NR‐V2X) networks, UAVs can be used as mobile base stations (UAV‐BS) to provide vehicular communications. However, effective power control and altitude planning algorithms are required to maximize the energy efficiency (EE) of these UAV‐BS systems. In this article, we propose an energy‐efficient power control and altitude planning algorithm for UAV‐BS in NR‐V2X networks. We formulate the optimization problem of maximizing the system's EE while considering the reliability requirements of vehicular users, the limitations of UAV‐BS hovering altitude, and the feasibility of transmission power levels. The problem is nonconvex, and we address this by reformulating it into a convex problem using the Dinkelbach and alternating optimization methods. The simulation results demonstrate that the proposed algorithm closely achieves the performance of exhaustive search while it is more computationally efficient. Moreover, our algorithm by jointly optimizing transmission power and hovering altitude performs better than other schemes proposed in the literature, as shown through our simulation results.

This paper employs full duplex (FD) and frequency reuse (FR) to improve the spectral efficiency while considering inter‐carrier interference (ICI) in 5G new radio vehicle‐to‐everything (NR‐V2X) networks. The quality of service of vehicle‐to‐vehicle (V2V) communications in such a system is affected by the self‐interference (SI) caused by FD, the co‐channel interference (CCI) caused by FR, and ICI caused by the Doppler effect. We present a performance analysis by proposing feasibility conditions for implementing FD and FR in NR‐V2X networks. We obtain a closed‐form expression for the maximum link distance between the transmitter and receiver of a link to provide reliable V2V communications. Our simulation results reveal the interplay between FD and FR technologies and demonstrate the performance gains of our proposed scheme compared to existing schemes in the literature.
