Millimeter Wave (mmWave) Massive Multiple Input Multiple Output (MIMO) has been a promising candidate for the current and next generation of cellular networks. The hybrid analogue/digital precoding will be a crucial ingredient in the mmWave cellular systems to reduce the number of Radio Frequency (RF) chains along with the corresponding energy and power consumption of the systems. In this paper, we aim to improve the energy efficiency of mmWave Massive MIMO by using a combination of high dimension analogue precoder and low dimension digital precoder. The spectral efficiency and the corresponding transmitted and consumed power of the mmWave Massive MIMO is formulated by taking all the consumed power from the transmitting side to receiving end into account. We propose the Power Controlled Energy Maximization (PCEM) algorithm in this paper, and the proposed algorithm works by controlling the transmission power to balance the improved radiated energy efficiency and the increased power consumption for a given number of transceiver chains. The simulation and analytical results show that the proposed algorithm performs better than the reference algorithms by maximizing the overall energy efficiency of the system without much complexity.

“…In terms of communication, there are various standards used in WSNs such as ZigBee, Bluetooth, Long range wide area network (LoRa WAN) and Sigfox. ZigBee requires low power consumptions and cost and are capable to deliver services such as e-mail, Internet, and the transfer of files [7], which brings a lot of benefits by considering the fact that the internet data traffic is increasing with every passing day [8,9]. Bluetooth also requires low power consumptions and is a cost-efficient device; however, it has less range compared to the ZigBee modules [10].…”

Radiation monitoring is essential for examining and refraining the unwanted situations in the vicinity of nuclear plants as high levels of radiation are quite dangerous for human beings. Meanwhile, Wireless Sensor Networks (WSNs) are proved to be an auspicious candidate to address that issue. Actually, WSNs are pretty beneficial to monitor an area with the aim of avoiding undesirable situations. In this paper, we have designed and implemented a cost-efficient radiation and the temperature monitoring system. We have used ZigBee to develop the sensor nodes, and the sensor nodes are instilled with the radiation and the temperature sensors. In addition, the Geiger Muller Tube (GM Tube), which is usually a reliable detector to monitor nuclear sites, is used to monitor the radiations. The designed system consists of two sensor nodes and the main node. The experimental results validate the designed system, where the communication between the nodes and the main node along with the inter-nodal communication are examined in order to ensure the smooth-running operation of the designed system.

“…where P doc , P cod is the power consumption during the process of decoding and coding of the received and the transmitted signals. As explained earlier, massive MIMO relies significantly on the accurate acquisition of the frequency response, so, the timely acquisition of the frequency response is of timely important, and the consumed power during the channel estimation P es can be expressed as [34]:…”

Massive Multiple Input Multiple Output MIMO technology is a promising candidate for the next generation of communication applications, which essentially group hundreds of transmitting antennas together at the base station and provides the higher energy and spectral efficiency. In this article, the transmitting antennas are assumed to be closely spaced at the base station, which in turn results into a mutual coupling effect between the antenna terminals. The optimal system parameters and the energy efficiency are computed by considering the mutual coupling effect between the antenna terminals. Mutual coupling effect is deeply investigated on the energy efficiency and the other optimal parameters. We propose the domain splitter algorithm for the optimization of energy efficiency and the computation of different optimal system parameters in this article. The computational complexity of the proposed domain splitter algorithm is not dependent on the number of transceiver chains, and the detailed comparison is presented between the proposed and the reference algorithms on the basis of the computational complexity, which shows the effectiveness of the proposed domain splitter algorithm.
