New physical layer key generation dimensions: subcarrier indices/positions-based key generation
(IEEE Communications Letters, 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
Novel nonorthogonal multi-access method for multi-user MIMO with antenna number modulation
(RS Open Journal on Innovative Communication Technologies, 2021)
Multiple Input Multiple Output with Antenna Number Modulation and Adaptive Antenna Selection (MIMO-ANM-AAS) has recently been proposed as an effective transmission method that can make the selection of antennas to be both ...
Is cell-free massive MIMO (CF-MMIMO) equivalent to the already existing and commercialized pCell technology?
(2021)
Distributed antenna system (DAS) is a highly diversified concept that can help lower radiated power, maximize coverage, and improve spectral efficiency. Yet, the most exciting feature of DAS is the distribution of remote ...
A belt-integrated piezoelectric energy harvester for wearable electronic devices
(Ferroelectrics, 2021)
This paper reports a novel piezoelectric energy harvester incorporated on a waistbelt for power generation from waist movements. The device is composed of multiple piezoelectric disks in 3 D-printed encapsulations and ...
NC-OFDM-SPM: a two-dimensional non-coherent modulation scheme for achieving the coherent performance of OFDM along with sending an additional data-stream
(RS Open Journal on Innovative Communication Technologies, 2021)
A promising candidate solution for reducing complexity in future wireless systems is the use of non-coherent designs; however, it is very well known in the literature that non-coherent schemes perform worse than their ...
An acoustic blood pressure sensing scheme using time of flight and shear wave elastography techniques
(Sensors and Actuators A-Physical, 2021)
A novel wearable blood pressure sensor scheme is presented. The design incorporates an array of piezoelectric transducers to transmit acoustic waves through the skin, and receive reflected echoes from an arterial wall. The ...
