Las señales electroencefalográficas son empleadas en el estudio de varias enfermedades, pero generan volúmenes de datos que dificultan su procesamiento. La compresión de estas señales permite disminuir el volumen de datos adquiridos, facilitando

Background and objective: T-wave alternans (TWA) is a fluctuation of the ST–T complex of the surface electrocardiogram (ECG) on an every–other–beat basis. It has been shown to be clinically helpful for sudden cardiac death stratification, thoug

Power line infrastructure is available almost everywhere. Positioning systems aim to estimate where a device or target is. Consequently, there may be an opportunity to use power lines for positioning purposes. This survey article reports the differen

The aim of this paper is to formulate the physical layer of the broadband and narrowband power line communication (PLC) systems described in standards IEEE 1901 and IEEE 1901.2, which address new communication technologies over electrical networks fo

Wavelet orthogonal frequency division multiplexing (OFDM) is one of the medium access techniques recommended by the IEEE 1901 working group for broadband communications over electrical networks, and is under consideration for IoT applications. This s

In this work, we derive a novel multicarrier modulation based on the Type-I even discrete cosine transform (DCT1e), which includes new procedures to carry out both the channel estimation and the signal reconstruction. By using a small number of train

A bandpass wavelet OFDM system, based on the time-domain waveform signals described in the standard IEEE Std. 1901-2010 for broadband power line communications, is presented. Several important aspects of the bandpass physical layer are reviewed, focu

Multicarrier modulation based on discrete cosine transform (DCT-MCM) is a candidate technique for future wireless communication. DCT-MCM provides a better usage of the spectrum, allowing for much lower out-of-band radiation than conventional OFDM. In

Analytical expressions of analog and digital α-spline filters with continuous transition bands are derived. Previous works based on β-spline functions consider the order of the spline function, which must be a natural number, as a parameter to shar

This paper aims at studying the achievable data rate of discrete cosine transform (DCT)-based multicarrier modulation (MCM) systems. To this end, a general formulation is presented for the full transmission/reception process of data in Type-II even D
