Rate splitting multiple access (RSMA) is a powerful and upcoming multiple access technique that can serve as a promising technology for 5G and beyond applications. Due to the increase in the number of indoor communication devices, the internet of eve

In this paper, we propose a height-dependency shaping parameter ( $m$ ) and a height-dependency path-loss exponent for modelling small-scale Nakagami- $m$ fading and a large-scale path-loss model for unmanned aerial vehicle (UAV)-assisted network cod

Buried fault is one of the important geological factors affecting the construction of transparent working face and the intelligent development of coal mine. Channel wave seismic exploration is a common method to detect fault at present. At present, t

This paper presents a novel three-time slot transmission protocol designed for energy-constrained two-way relay systems. In a departure from traditional energy sources, our approach serves a dual purpose by not only providing power to the system but

Most wireless communication technologies for Internet of Things (IoT) applications face the bottleneck of dense and large-scale use cases. One solution to this problem is a periodic channel reservation strategy, in which only a small group of station

In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branc

Dispersion curves of Rayleigh channel waves may have “cross” between the fundamental and first higher order modes either in the phase velocities or in group velocities in the low frequency band. It was observed that such phenomenon can lead to wr

In this paper, the least-squares channel estimation (LSCE) is investigated for Massive-Multiple-Input Multiple-Output (Ma-MIMO) OFDM systems based on pilot tones. The uplink (UL) transmission is considered, in which a channel estimation approach is p

Aiming at the problem that the communication environment is complex and the peak-to-average ratio of the baseband receiving signal of dPMR digital intercom is too large, a strategy for automatic gain control of signals processed by Gaussian channel a
