Optimized Reception Sensitivity of WBAN Sensors Exploiting Network Coding and Modulation Techniques in an Advanced NB-IoT

“…The communication in [23] shows an innovative test bench for evaluating the quality of the sensibility of a vehicle's radio reception. To improve the energy efficiency of receiver-dominated nodes in IoT networks, the authors in [24] offer Receiver-Sensitivity Control (RSC). The sensitiv-ity restrictions of the Sensitivity in IEEE 802.15.4 standard 2.4 GHz PHY Receivers for the personal wireless and sensor networks are discussed in [25].…”

Receiver Design With an Adjustable Energy-Signal-Quality Tradeoff for IoT Networks

“…The mentioned papers thus introduce adjustable component-level knobs that allow to trade signal-recovery efforts for consumed energy. On the network level, [7] shows that such techniques indeed significantly increase energy efficiency.…”

“…We propose a system-level design of a receiver providing an appropriate combination of adjustable analog and digital elements that enable the reconfiguration of the signal-quality-energy tradeoff to meet communication quality requirements at hand, given the channel conditions and incoming signal quality. In contrast to the hypothetic network-level operation modes used in [7],…”

“…Run-time adaptation has been demonstrated in a variety of receiver components such as the Low Noise Amplifier (LNA) [3], the LNA and Mixer combination [4], the Analog-to-Digital Converter (ADC) [5], and the digital baseband [6]. Recent work demonstrates how to configure an adjustable receiver at network level [7]. Yet, the systemlevel combination of adjustable components and their impact at the system level is not sufficiently explored.…”

Evaluation of Radio Communication Links of 4G Systems

“…A receiver is characterized by its sensitivity (S) which is the minimum power level of the received signal that allows the reception of the signal (minimum reception power level) [ 16 ]. It is given by the following formula: S = 10 log(K. T. BRx) + SINR required + NF, …”
