Abstract: Abstract The paper ameliorates spectral-and-energy efficiencies and reliability-and-security performances for uplink transmission under fading, shadowing, path-loss, and hardware imperfection (HWi) by applying energy harvesting (EH), non-orthogonal multiple access, multi-antenna power beacon, and jamming. To do this, we provide explicit expressions of reliability-and-security performances subject to EH nonlinearity. Various results validate these expressions and expose considerable performance mitigation caused by channel impairments, HWi, and EH nonlinearity. Furthermore, desired reliability/security performances are reached by properly selecting a group of parameters. Nevertheless, security remains high and varies slightly with these parameters whereas reliability changes dramatically with them. This implies that achieving high reliability/security performances is possible. Noteworthily, the proposed communication paradigm attains optimum performance by adopting time splitting parameter properly.
