| dc.description | Con la llegada de las aplicaciones multimedia de banda ancha y la creciente demanda de acceso a la red de información de los dispositivos móviles, es esencial mejorar la eficiencia en la utilización del espectro electromagnético para cubrir las necesidades de altas tasas de bits proporcionales a los servicios multimedia. Por tal razón, la radio cognitiva se ha convertido en uno de los paradigmas más investigados en las comunicaciones de radio para optimizar el uso del espectro radioeléctrico. Dentro de la movilidad espectral de las redes de radio cognitiva, las estrategias de handoff proactivas resultan ser las más beneficiosas para el usuario primario, dado que no existe periodo de interferencia en el cual coexistan los dos usuarios (primario y secundario); sin embargo, la problemática de esta estrategia radica en la precisión de la predicción de la llegada del usuario primario, es decir, en la predicción de la ocupación espectral de la banda licenciada. El presente libro plantea el desarrollo de un modelo de predicción de la ocupación espectral, que tenga en cuenta las características relevantes del comportamiento del espectro, a partir de mediciones realizadas en un entorno urbano, el cual pueda contribuir al mejoramiento del handoff proactivo y, por ende, del desempeño de las redes de radio cognitiva. | spa |
| dc.description.abstract | With the arrival of broadband multimedia applications and the growing demand for access to the information network of mobile devices, it is essential to improve the efficiency in the use of the electromagnetic spectrum to cover the needs of high bit rates proportional to the services multimedia. For this reason, cognitive radio has become one of the most researched paradigms in radio communications to optimize the use of the radio spectrum. Within the spectral mobility of cognitive radio networks, proactive handoff strategies turn out to be the most beneficial for the primary user, given that there is no interference period in which the two users (primary and secondary) coexist; However, the problem with this strategy lies in the precision of the prediction of the arrival of the primary user, that is, in the prediction of the spectral occupancy of the licensed band. This book proposes the development of a spectral occupancy prediction model, which takes into account the relevant characteristics of the spectrum behavior, based on measurements carried out in an urban environment, which can contribute to the improvement of proactive handoff and, therefore, hence, the performance of cognitive radio networks. | spa |
