Pre-seismic Electromagnetic Perturbations in Two Earthquakes in Northern Greece

TL;DR: In this paper, a logit regression model was applied to the data to examine whether ELF perturbations could be considered as precursors of seismic activity, and a simple nonlinear statistical model supported the idea that there is some kind of physical interaction between seismic and atmospheric ELF activities.
Journal ArticleDOI

Significant ELF perturbations in the Schumann Resonance band before and during a shallow mid-magnitude seismic activity in the Greek area (Kalpaki)

TL;DR: In this article, strong ELF perturbations in the Schumann Resonance band (0-50 Hz) were detected in the North of Greece close to the village of Kalpaki during a shallow (17 km) mid-magnitude earthquake (5,3R) and the post-seismic sequence that followed it.
Journal ArticleDOI

A new portable ELF Schumann resonance receiver: design and detailed analysis of the antenna and the analog front-end

TL;DR: The primary objective of this work was to design and implement a stand-alone, portable, and low-cost receiver able to measure as much Schumann resonance harmonics as possible, as well as detailed analysis of the efficient induction coil magnetic antenna and the low-noise amplifying-filtering chain.
Journal ArticleDOI

Preliminary BER Study of a TC - OFDM system operating under noisy conditions

TL;DR: In this article, the authors simulated their enhanced OFDM platform based on Turbo Coding (TC) in the presence of a noisy channel (AWGN, Phase noise, Rician noise, ITU PA3) exhibiting excellent BER performance.
Proceedings ArticleDOI

In depth analysis of noise effects in orthogonal frequency division multiplexing systems, utilising a large number of subcarriers

TL;DR: In this paper, the relationship between BER performance in noisy environments and the number of transmitted subcarriers was investigated. But the authors did not consider the effect of various noise types, such as complex Rayleigh fading, complex rician noise, AWGN and phase noise.
