In this paper, we propose a novel Superimposed Training (ST) technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, where data and training signals are divided in orthogonal code domains in order to ...

A family of Nyquist-I pulses called sinc parametric linear combination pulse (SPLCP) is proposed. It is characterized by two novel design parameters that provide additional degrees of freedom to minimize the intercarrier ...

It is well-know that carrier frequency offset in the subcarriers of orthogonal frequency division multiplexing (OFDM) leads to intercarrier interference (ICI); therefore, system degradation occurs. Nevertheless, this issue ...

Neste trabalho apresenta-se as atividades desenvolvidas durante o período de vigência da bolsa de iniciação científica entre setembro de 2021 e agosto de 2022. As atividades foram realizadas no LCS (Laboratório de Comunicações, ...

As the demand for better performance increases in next-generation networks, such as 5G technologies, more efficient modulation techniques are required. In this work, we evaluate the performance of the improved parametric ...

This paper presents a theoretical model developed for estimating the power, the optical signal to noise ratio and the number of generated carriers in a comb generator, having as a reference the minimum optical signal do ...
