Peak signal power is an important factor in the implementation of multicarrier (MC)
modulation schemes, like OFDM, in wireless and wireline communication systems. This …

The high peak to average power ratio (PAPR) levels associated with multicarrier systems
require the use of linear power amplifiers (PA) with large dynamic range. Unfortunately …

Web Services are commonly used to implement service oriented architectures/applications.
Service-oriented applications are large-scale distributed applications, typically highly …

Tras una larga gestación y una corta vida, el libro “Comunicaciones digitales” fue
descatalogado en 2010. Tras volver el copyright a los autores analizamos las distintas …

Low-density parity-check (LDPC) coded orthogonal frequency division multiplexing (OFDM)
is proposed as an efficient coded modulation technique suitable for optical communication …

With the advent of new high data rate wireless applications, as well as growth of existing
wireless services, demand for additional bandwidth is rapidly increasing. Existing" command …

Multicarrier modulation in the form of orthogonal frequency division multiplexing (OFDM) has
prevailed in recent broadband wireless systems over radio channels. In this senior design …

In this paper a front-end noise power and SNR estimation method based on one OFDM
preamble is proposed and compared with previously published SNR estimators-none of …

The radio spectrum is becoming increasingly congested everyday with emerging
technologies and with the increasing number of wireless devices. Considering the limited …

This paper proposes a relay-assisted space-frequency block code (SFBC) for single carrier
frequency-domain equalization (SC-FDE) in a distributed fashion. The proposed scheme …
