The increase in the peak-to-average power ratio (PAPR) is a well known but not sufficiently addressed problem with data-dependent superimposed training (DDST) based approaches for channel estimation and synchronization in digital communication links. In this article, we concentrate on the PAPR analysis with DDST and on the spectral regrowth with a nonlinear amplifier. In addition, a novel Gauss...

This paper presents a low power low voltage positive third generation current conveyor using four simple first generation current conveyors. It is designed and simulated in a standard 0.18um TSMC 1P, 6M CMOS process. This current conveyor design with the help of design architect and IC station (mentor graphics). Its DC, AC and transient analysis is carried out with ELDO tool. Its pre layout and...

Superconducting fault current limiters (SFCL) can be an alternative to conventional devices limiting short-circuit currents in power systems. SFCL use high-temperature superconducting tapes of the second generation (HTS 2G) SFCL, which, after reaching characteristic critical tape, go into resistive state (quenching), current. The determines moment activation SFCL. Therefore, its value should no...

Microwave Interferometer in the Limiter Shadow (MILS) is a new diagnostic, installed on ASDEX Upgrade for electron density measurements far Scrape-Off Layer (SOL). At chosen frequency of 47 GHz, region varies within several centimetres before and after limiter, depending density. 200 kHz bandwidth allows resolving transient events such as edge localized modes filaments turbulence filaments. The...

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. Due to the difficulty in power network reinforcement and the interconnectio...
