Análisis y comparación de ISDB-T utilizando modulaciones OFDM y CC-OFDCM
(2019-01)
La Televisión Digital Terrestre está orientada a sustituir las transmisiones de televisión analógica, al utilizar
la modulación OFDM (multiplexación por división de frecuencias ortogonales), con esta modulación se puede ...
Extensive Comparisons of Optical Fast-OFDM and Conventional Optical OFDM for Local and Access Networks
(Optical Soc Amer, 2012-10-01)
A performance comparison between a recently proposed novel technique known as fast orthogonal frequency-division multiplexing (FOFDM) and conventional orthogonal frequency-division multiplexing (OFDM) is undertaken over ...

Estimación de canal en OFDM
(CRUC-IUA-UNDEF, 2009)
Debido al gran crecimiento de las comunicaciones digitales, la necesidad de transmisión de datos en altas velocidades es cada vez más requerida, es así que surge la modulación multiportadora. OFDM es un sistema que utiliza ...
Suppressing the effect of ICI power using dual sinc pulses in OFDM-based systems
(Elsevier, 2016)
Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
Exploiting spatial diversity in overloaded MIMO LDS-OFDM multiple access systems
(IEEE, 2017)
In this paper, we consider the deployment of multiple antennas as a way to exploit spatial diversity in the uplink of multiple access systems that adopt low-density spreading (LDS) with orthogonal frequency-division ...
