Distributed-Based Transversal Filter Approach for Spectrally Encoded Multi-Gb/s CDMA Systems
(Revista Computación y Sistemas; Vol. 16 No. 4, 2012-12-10)
Abstract: A novel distributed transversal filter technique for code division multiple access systems is proposed. It is observed that the distributed amplifier principle underlying the filter approach enables the generation ...
SIR optimization in wavelength-hopping time spreading optical code routed networks

Improved spectral observations of equatorial spread F echoes at Jicamarca using aperiodic transmitter coding
(Elsevier, 2004-11)
We present preliminary radar results obtained with a new method of spectrum estimation of moderately overspread equatorial spread F (ESF) echoes over Jicamarca. This new method is similar to the classical pulse-to-pulse ...

Optimal Code Set Selection and Security Issues in Spectral Phase-Encoded Time Spreading (SPECTS) OCDMA Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
In this paper, we perform a thorough analysis of a spectral phase-encoded time spreading optical code division multiple access (SPECTS-OCDMA) system based on Walsh-Hadamard (W-H) codes aiming not only at finding optimal ...
Spread spectrum orthogonalization of superimposed training signals in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2017-10)
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 ...
Um estudo comparativo do desempenho de algumas famílias de sequências de códigos lineares espalhados em um sistema DS-SSMAA comparative study of the performance of some families of linear code sequences spread over a DS-SSMA system

Language Spread and Shift
(Universidad de La SabanaDepartamento de Lenguas y Culturas Extranjeras, 2018-06-14)
By the end of this lesson the students will be able to understand the way language spread around the world and how is the behavior and the rol that it takes in each culture, offering the english language as the best way ...
