Abstract Non-orthogonal multiple access (NOMA) technology provides an effective solution to massive with a high data rate demand in new-generation mobile networks. The paper combinations NOMA and simultaneous wireless information power transfer (SWIPT) relay maximize the sum downlink system. To that end, it is critical how select effectively users system allocation for user. This proposes user ...

In this paper, simultaneous wireless information and power transfer based on time–frequency block allocation (TFBA-SWIPT) is proposed to save the energy of an orthogonal frequency-division multiplex (OFDM) decode-and-forward cooperative communication system, by allocating different resource blocks for decoding harvesting at relay destinations. The joint optimized maximize transmission rate dest...

In this paper, we consider multiuser simultaneous wireless information and power transfer (SWIPT) for cognitive radio systems where a secondary transmitter (ST) with an antenna array provides information and energy to multiple single-antenna secondary receivers (SRs) equipped with a power splitting (PS) receiving scheme when multiple primary users (PUs) exist. The main objective of the paper is...

In this paper, a nonorthogonal multiple access based cooperative relaying system (NOMA-CRS) is consideredto increase spectral efficiency. Besides, the simultaneous wireless information and power transfer (SWIPT) proposedfor relay in NOMA-CRS. SWIPT-NOMA-CRS, three different energy harvesting (EH) protocols, sharing(PS), time sharing (TS) ideal protocols are implemented. The outage performances ...

System splitting problem, also known as controlled system separation problem, is to determine the proper splitting points for splitting the entire power network into islands when island operation of system is unavoidable. By “proper” we mean that the splitting strategies should guarantee both the power balance and satisfaction to capacity constraints of transmission lines and other facilities i...

Reconfigurable intelligent surface (RIS)-based communication networks promise to improve channel capacity and energy efficiency. However, the promised gains could be negligible for passive RISs because of double pathloss effect. Active can overcome this issue they have reflector elements with a low-cost amplifier. This letter studies active RIS-aided simultaneous wireless information power tran...

In this paper we consider a heterogeneous network which consists of a macro base station and some pico base stations utilizing massive MIMO and MIMO techniques, respectively. A central software-defined mobile network (SDMN) controller is adopted in order to provide user association and energy scheduling. The users are considered battery limited and are capable of simultaneous wireless informati...

this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
