In this work, we introduce and evaluate the performance of a novel family of Nyquist (intersymbol interference free) pulses that outperform several existing ones available in the open technical literature. The proposed pulse design is based on a poly

In 2014–2018, four strong earthquakes occurred in the Ionian Sea, Greece. After these events, a rich aftershock sequence followed. More analytically, according to the manual solutions of the National Observatory of Athens, the first event occurred

We present analytical results on the average probability of error (PER) performance of an optically pre-amplified pulse-position modulation (PPM) receiver under Malaga- M fading. The results are in the form of a finite sum whose number of terms depen

We present exact and approximate results on the average probability of error (PER) for pulse position modulation (PPM) in pre-amplified optical wireless communication systems with diversity. The approximate results are obtained by combining a new mat

We present analytical results on the average bit error probability (ABEP) of an optically pre-amplified pulse-position-modulation (PPM) receiver that operates under fading and pointing errors. The analytical description enables the efficient calculat
