Noise and Interference in Power Line channels
(IEEEMéxico, 2009)
The power lines grid has been utilized for lowdata-rate applications for some generations. Today, many are the challenges that this technology has presented to the Communications Engineering, when it is intended to offer ...
Desarrollo y simulación de un modelo de transceptor basado en Prime para simulación sobre canal PLC
(European Scientific Institute, 2018-09)
La elección de la técnica de modificación para un sistema de comunicaciones depende en gran medida de la naturaleza y características del
medio en el que tiene que operar (Hrasnica et al., 2005). En un sistema PLC (Power ...
Statistical independence of reflection and transmission coef-ficients on plt due to system loads
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2014-07-30)
This paper presents the theoretical development of the covariance between reflection and transmission coefficients caused by system loads in electric grids. This result allows the calculation of the expected value and ...
Modulação quantizada para sistemas com codificação wavelet sujeitos ao desvanecimento rayleigh
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2009-03-12)
Wavelet coding is an efficient technique to overcome the multipath fading effects, which are characterized by fluctuations in the intensity of the transmitted signals over wireless channels. Since the wavelet symbols are ...
Techniques d’Estimation de Canal et de Décalage de Fréquence Porteuse pour Systèmes Sans-fil Multiporteuses en Liaison Montante
(2011-12-14)
Multicarrier modulation is the common feature of high-data rate mobile wireless systems. In that case, two phenomena disturb the symbol detection. Firstly, due to the relative transmitter-receiver motion and a difference ...
