“…In the most of the existing works concerning the NOMA aided WIT and SWIPT systems, the WIT performance was always characterised by the classic Shannon-Hartley channel capacity, which inherently assumes infinite Gaussiandistributed continuous channel input. However, the attainable performance is always overestimated, since the channel input of any practical WIT or SWIPT system is normally finite and discrete [23]. As a result, we may attain more accurate performance when a practical modulator is considered.…”

Radio frequency (RF) signals can be relied upon for conventional wireless information transfer (WIT) and for challenging wireless power transfer (WPT), which triggers the significant research interest in the topic of simultaneous wireless information and power transfer (SWIPT). By further exploiting the advanced non-orthogonal-multiple-access (NOMA) technique, we are capable of improving the spectrum efficiency of the resource-limited SWIPT system. In our SWIPT system, a hybrid access point (H-AP) superimposes the modulated symbols destined to multiple WIT users by exploiting the power-domain NOMA, while WPT users are capable of harvesting the energy carried by the superposition symbols. In order to maximise the amount of energy transferred to the WPT users, we propose a joint design of the energy interleaver and the constellation rotation based modulator in the symbol-block level by constructively superimposing the symbols destined to the WIT users in the power domain. Furthermore, a transmit power allocation scheme is proposed to guarantee the symbol-error-ratio (SER) of all the WIT users. By considering the sensitivity of practical energy harvesters, the simulation results demonstrate that our scheme is capable of substantially increasing the WPT performance without any remarkable degradation of the WIT performance.

“…Next-generation communication systems require self-sustainability wireless nodes to maintain a high data rates network and guarantee quality of service (QoS) [ 1 ]. Radio frequency (RF) signal-based simultaneous wireless information and power transfer (SWIPT) is a promising technique for prolonging the lifetime of continuous network operation [ 2 , 3 ]. SWIPT can jointly extract information and replenish energy from the same signal by performing two circuits to separate the information processing and power transfer alternatively [ 4 , 5 ].…”

The secure full-duplex (FD) simultaneous wireless information and power transfer (SWIPT) system and non-orthogonal multiple access (NOMA) have been deemed two promising technologies for the next generation of wireless communication. In this paper, the network is combined with device-to-device (D2D) and a practical bounded channel state information (CSI) estimation scheme. A system total transmit power minimization problem is studied and formulated as a multi-objective optimization (MOO) problem via the weighted Tchebycheff approach. A set of linear matrix inequalities (LMI) is used to transform the non-convex form of constraints into the convex form. Considering the imperfect CSI of the potential eavesdropper for robust power allocation, a bounded transmission beamforming vector design along with artificial noise (AN) is used, while satisfying the requirements from the secrecy rates as well as the energy harvesting (EH) task. Numerical simulation results validate the convergence performance and the trade-off between the uplink (UL) and downlink (DL) data transmit power. It is also shown that by FD and NOMA, the performance of the proposed algorithm is higher than that of half-duplex (HD) and orthogonal multiple access (OMA).

“…Fortunately, there exist a number of heuristic algorithms [41] for its reduced form, known as the quadratic assignment problem, that result in high-quality solutions over the quadratic assignment problem library dataset. The authors of [42] argued that the simultaneous wireless information and power transfer system designed using Gaussian distributed input signals may result in degradation of performance. Thus, they provided a guide for coding-controlled single and multi-user simultaneous wireless information and power transfer systems.…”

With the surge of ubiquitous demand for high-complexity and quality mobile Internet-of-things (IoT) services, new cooperative relaying paradigms have emerged. Motivated by the long and unpredictable end-to-end communication in relay-aided IoT networks, there is a need to introduce novel modulation schemes for very low bit error rate (BER) communications. In this paper, a practical modulation mapping scheme has been proposed to reduce decoding errors. Specifically, a hybrid automatic repeat request (HARQ) system has been used with an intermediate relay to transfer a message from a source to a destination. The design of modulation mapping has been optimized by first formulating the objective as the quadratic assignment problem. Later, the solution to the mapping problem is provided using an iterative search method. To validate the proposed solution, extensive simulations have been performed in MATLAB. The results show that the proposed solution outperforms the conventional relay retransmission and the heuristic design approaches.
