A Uniform-Forcing Transceiver Design for Over-the-Air Function Computation

TL;DR: A novel uniform-forcing transceiver design is proposed for over-the-air function computation to compensate the non-uniform fading of different sensors and is able to achieve significant performance gain with low complexity.
Journal ArticleDOI

Over-the-Air Computation for IoT Networks: Computing Multiple Functions With Antenna Arrays

TL;DR: This paper proposes a novel transmitter design at the IoT devices with zero-forcing beamforming to cancel the intranode interference and uniform-forcing power control to compensate the nonuniform fading and proposes a corresponding signaling procedure utilizing the “OR” property of the wireless channel.
Proceedings ArticleDOI

A novel SNR estimation algorithm for OFDM

TL;DR: Simulation results show that the new SNR estimation algorithm performs better in large Doppler frequency environments and is insensitive to the statistical characteristics of the channel.
Journal ArticleDOI

Power-Constrained Edge Computing With Maximum Processing Capacity for IoT Networks

TL;DR: An optimization problem of APC with a general utility function is formulated and several fundamental criteria for resource allocation are derived and a binary-search water-filling algorithm is proposed to solve the power allocation between local CPU and multiple subcarriers.

Energy-Efficient Link Adaptation on Rayleigh Fading Channel for OSTBC MIMO System With Imperfect CSIT

TL;DR: This work proposes an energy-efficient adaptive transmission scheme for multiple-input–multiple-output (MIMO) beamforming systems with orthogonal space–time block coding (OSTBC) based on imperfect channel state information at the transmitter (CSIT) to maximize the energy efficiency subject to an instantaneous bit-error-rate constraint.
