Power reconfigurable receiver model for energy-aware applications

Abstract

Abstract-This paper presents a reconfigurable receiver model whose purpose is to enable the study of reconfiguration strategies for future energy-aware and adaptive transceivers. This model is based on Figure of Merits of measured circuits. To account for real-life RF interference mechanisms, a link quality estimator is also provided. We show that adapting the receiver performance to the channel conditions can lead to considerable power saving. The models proposed can easily be implemented in a wireless network simulation in order to validate the value of a reconfigurable architecture in real-world deployment scenarios.

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

“…The proposed design comes with a communication-level model that relates receiver sensitivity to energy consumption per successfully received bit. This model expands the receiver model described in [13] in several aspects. Compared to [13], we use measurements published on real adjustable components instead of published figures of merits collected from nonadjustable components.…”

Furthermore, we introduce channel coding into the system as a technique to enhance the signal quality.…”

Estimation of a 10 Gb/s 5G Receiver's Performance and Power Evolution Towards 2030

“…In this study it is therefore assumed that the performance of the LNA, mixer and other active components evolve at the same pace because they change CMOS technology node concurrently. Two existing power models also estimate that the power consumption of the LNA and mixer only differ 5-17 % [4,5]. There are a few LNA performance evolution studies available in literature and therefore it is selected as the RF Front End component in this work.…”

“…1 is used, and therefore a single receive chain per Component Carrier (CC) for CA and per MIMO stream, composed of a common LNA, a mixer for each I and Q branch, and a Voltage Controlled Oscillator (VCO). Based on [4,5] it is assumed that the mixers and VCOs will consume roughly the same power as the LNA, while the filters and the Automatic Gain Control (AGC) are assumed to have negligible power consumption. By combining the estimates of sec.…”

Deployment and implementation strategies for massive MIMO in 5G

“…Note that we do not model possible power savings of combining multiple ADCs in one IC to share voltage reference source, digital control and so forth. To calculate the total power consumption the RF power model from [20] is used, covering both the I and Q branch and includes the power consumption of the low noise amplifier, mixers, the shared voltage controlled oscillator and other phase locked loops components, variable gain amplifiers and analog baseband filters. The power is a function of noise figure and third order intercept point performance, because the components in general are not considered BW dependent.…”
