A thorough analysis has been carried out to study and compare the sensitivity of two signaling methods (PAM4 and ENRZ) to inter-symbol interference (ISI). While both signaling methods are considered to be major candidates for implementing 56+ Gbps serial c ...

LoRaWAN is a low-power wireless technology that provides long-range connectivity to battery-powered Internet of Things (IoT) devices. To minimize the energy consumption of the IoT nodes, LoRaWAN networks use for the uplink a pure non-slotted ALOHA multiple ...
This paper presents the design and analysis of a serial link transceiver (TRX) architecture employing analog multi-tone (AMT) signaling for chip-to-chip communication. Multi-tone single-sideband (SSB) signaling scheme is proposed in TRX architecture in ord ...
Imaging techniques in radio interferometry often face a significant challenge posed by the large number of antenna signals received, from which the image information needs to be extracted. Beam- forming is envisaged to reduce the rate required for transpor ...
In this paper, a 41 x 42.2 mm2 ultra-wide band (UWB) diversity antenna is designed to operate in the frequency band 5.45- 7.45 GHz with the isolation better than 15dB. To achieve omnidirectional coverage pattern diversity is applied. The proposed design is ...

Abstract: In this paper, we consider communication on a two-hop channel in which a source wants to send information reliably and securely to the destination via a relay. We consider both the untrusted relay case and the external eavesdropper case. In the u ...
