Correlated shadow fading has a detrimental effect on the performance of wireless systems. Neglecting shadowing correlations could lead to inaccurate simulation results and unreliable wireless system design. In this paper, we propose and analyze a correlated shadow fading model based on Gaussian random fields. The model enables the generation of spatially(More)
The non-orthogonal multiple access (NOMA) is regarded as a promising multiple access technique for 5G networks. In this research, we consider the joint transmission (JT) NOMA for a Coordinated Multi-Point (CoMP) system, and propose a novel opportunistic NOMA (ONOMA) scheme. This aims to improve the efficiency of the successive interference cancellation(More)
Wireless links are typically modeled in isolation as independent and parallel links. However, in reality, there is often a correlation in defects and impairments between collocated links. The spatial correlation of shadowing among proximate wireless links has been frequently observed. Although different types of correlated shadowing models have been(More)
