Analysis of the energy harvesting non-orthogonal multiple access technique for defense applications over Rayleigh fading channel conditions

Abstract

The energy harvesting (EH) technique has ignited a rising research interest due to its ability to enhance the battery power of user equipment by harvesting energy by using a simple radio frequency circuit. In this paper, the simultaneous wireless information and power transfer non-orthogonal multiple access (NOMA) technique is investigated over Rayleigh fading channel conditions. EH NOMA improves the power efficiency, and it results in better throughput as compared to conventional NOMA techniques. In this paper, we investigate the achievable data rate and the outage probability performance of the near user, also called the relay user (RU), and the far user (FU). It can clearly be shown that the RU data rate is saturated and at 1 bits/s/Hz will become constant, while the FU data rate increases with an increase in transmitted power. It is seen by analysis that the RU data rate would saturate due to EH. It is further shown that with a transmitted power of 18 dBm, the net output of the FUs is readily shown to be based around a value of 2.80 bits/s/Hz. In comparison, it is shown that the FU’s instantaneous information rate dropped below the target data rate.

Investigation of Vehicular S-LSTM NOMA Over Time Selective Nakagami-m Fading with Imperfect CSI

“…5G, IoT and multimedia applications place strict demands on capacity and user access. The NOMA scheme [13], [14] offers an optimistic answer to these challenges. MIMO, cognitive cooperative relaying, full-duplex relaying, millimeter-wave, and other technologies have been employed in conjunction with NOMA to increase throughput and guarantee user fairness in a wide range of fading channel distributions [15], [16].…”

“…This method allows you to communicate anywhere to generate energy and connect billions of 5G IoT wirelessly at any time. 17,18 In addition, many analytical studies at work examine the same signal for both decoding and equalization of information. 19,20 However, due to the limitations of the RF circuit, this simultaneous transmission is not possible.…”

An Investigation of the MIMO Space Time Block Code Based Selective Decode and Forward Relaying Network over n-u Fading Channel Conditions

“…With the explosive growth of cellular traffic, researchers are increasingly interested in improving performance of wireless networks in real-time propagation conditions. Therefore, they focus on the different systems, including massive multiple-input multiple-output (m-MIMO), device-to-device (D2D) communication, spatial modulation (SM) techniques, machine-to-machine (M2M) communication, non-orthogonal multiple access (NOMA) systems, and cooperative wireless communications over real-time propagation environments [1]- [4]. The use of multiple-input-multiple-output (MIMO) networks over multipath fading links can significantly increase spectral efficiency (SE) and quality of service (QoS).…”

“…As a result, space time block code (STBC) introduces the cooperative diversity (virtual MIMO) approach to mitigate multipath fading and to increase diversity gains (DGs). In a 1 2 transmit diversity system, Alamouti suggested in [4] that orthogonal space-time codes achieve DG levels that are comparable to those of MRC systems. The increasing popularity of smartphones and tablets has recently accelerated the use of wireless local area networks (LAN).…”
