Design and performance analysis of low phase noise LC-voltage controlled oscillator
Voltage controlled oscillator (VCO) offers the radio frequency (RF) system
designer a freedom to select the required frequency. Today’s wireless
communication system imposes a very stringent requirement in terms of
phase noise generated in VCO.…

Dickson voltage multiplier with 1 to 6 stages for dual-band rectifiers (2.45/5.8 GHz) with low input power
This paper presents the design of highly efficient rectifiers that can operate
at WiFi frequencies (2.45 GHz and 5.8 GHz) and match low input power.
The designed dual-band rectifiers use multi-stage dickson voltage multipliers
(DVM) (from 1 to 6…

Estimating losses at 40-GHz downlink using non-meteorological techniques in heavy rain areas
The advancement of satellite communication has arisen tremendously where
higher capacity communications systems are needed. Most satellite
engineers are shifting to Ka, Q, and V-band upcoming since the low
frequencies such as below 10 GHz are…

Experimental of vectorizer and classifier for scrapped social media data
In this study, we used several classifiers and vectorizers to see their effect on
processing social media data. In this study, the classifiers used were random
forest, logistic regression, Bernoulli Naive Bayes (NB), and support vector
clustering…

LSKA-ID: A lightweight security and key agreement protocol based on an identity for vehicular communication
Recently, a huge effort has been pushed to the wireless broadcasting nature
in the open area. However, the vehicular ad hoc network (VANET) is
disposed to various kinds of attacks. Hence, keeping the security in VANET is
the most critical issue…
