“…Again, its performance is also improved as the correlation length increases. As we know, the success probability of channel access is one of vital evaluation criteria of access efficiency in satellite RA, which can be utilized to indicate energy efficiency [36], [37] and access delay. To demonstrate the performance benefit of channel access success probability, we compare the proposed method with our earlier method given in [19], wherein CFO is set to 0 for fair comparison.…”

Satellite communication system is expected to play a vital role for realizing various remote internet of things (IoT) applications in 6G vision. Due to unique characteristics of satellite environment, one of the main challenges in this system is to accommodate massive random access (RA) requests of IoT devices while minimizing their energy consumptions. In this paper, we focus on the reliable design and detection of RA preamble to effectively enhance the access efficiency in highdynamic low-earth-orbit (LEO) scenarios. To avoid additional signaling overhead and detection process, a long preamble sequence is constructed by concatenating the conjugated and circularly shifted replicas of a single root Zadoff-Chu (ZC) sequence in RA procedure. Moreover, we propose a novel impulse-like timing metric based on length-alterable differential cross-correlation (LDCC), that is immune to carrier frequency offset (CFO) and capable of mitigating the impact of noise on timing estimation. Statistical analysis of the proposed metric reveals that increasing correlation length can obviously promote the output signal-to-noise power ratio, and the first-path detection threshold is independent of noise statistics. Simulation results in different LEO scenarios validate the robustness of the proposed method to severe channel distortion, and show that our method can achieve significant performance enhancement in terms of timing estimation accuracy, success probability of first access, and mean normalized access energy, compared with the existing RA methods.

“…As the wavelength of the mileage is quite little, it uses both transmission and reception spatial multiplexing techniques. In the millimeter range, massive MIMO will play an important role (Hao et al 2019). The transmission node can transmit a direct signal to the appropriate receiver using suitable signal processing techniques.…”

Simultaneous wireless information and power transfer (SWIPT) has given new opportunities for dealing with the energe shortage problem in wireless networks.Green transmission for 5G cellular networks of mobile cloud access networks based on SWIPT is being examined. Considering SWIPT as a future potential solution for increasing the battery life, this technique improves energy efficiency (EE). One of the technologies is wireless communication to transfter the power used to give sufficient resources to energy-constrained networks that have consequences for 5G and the internet of things (IoT), energy efficiency, co-operative communication and suitable are supported by the SWIPT. To enhance the capacity, data rate improvement, and better performance of quality of services of further networks. In addition to these criteria, it is also our moral responsibility to protect the environment of wireless networks by lowering power usage. As a result, green communication is a critical requirement. We looked at a variety of strategies for power optimization in the impending 5G network in this article. The utilization of relays and microcells to enhance the network’s energy efficiency is the main focus. The many relaying scenarios for next-generation networks have been discussed.

“…The underlying concept of SWIPT is to utilize the RF signal to simultaneously transmit information and energy through the wireless medium [14], [15]. Theoretically, this can be accomplished by decomposing the received signal into two parts at the receiver end, namely, information decoding (ID) and energy harvesting (EH) [16].…”

A Joint Beamforming and Power-Splitter Optimization Technique for SWIPT in MISO-NOMA System

et al. 2021

In this paper, we propose a joint beamforming and power-splitter optimization technique for simultaneous wireless power and information transfer in the downlink transmission of a multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) system. Accordingly, each user employs a power splitter to decompose the received signal into two parts, namely, the information decoding and energy harvesting. The former part is used to decode the corresponding transmitted information, whereas the latter part is utilized for harvesting energy. For this system model, we solve an energy harvesting problem with a set of design constraints at the transmitter and the receiver ends. In particular, the beamforming vector and the power splitting ratio for each user are jointly designed such that the overall harvested power is maximized subject to minimum per-user rate requirements and the available power budget constraints at the base station. As the formulated problem turns out to be non-convex in terms of the design parameters, we propose a sequential convex approximation technique and demonstrate a superior performance compared to a baseline scheme.INDEX TERMS Non-orthogonal multiple access (NOMA), energy harvesting, simultaneous wireless power and information transfer (SWIPT).
