Análisis del desempeño de esquemas codificación turbo y convolucional en el enlace de bajada de ITE-advanced

Juan Rodriguez, Christian Vega Caicedo, Sebastian Guerrero, John Barco Jiménez

Resumen


Este artículo presenta un análisis comparativo del desempeño de los codificadores turbo y convolucional aplicables al enlace de bajada de LTE-A, técnología de acceso que se encuentra en auge en la region. Para ello se desarrollaron modelos de simulación a nivel de enlace en Simulink® a partir de recomendaciones de la ETSI que permitieron caracterizar la respuesta de los codificadores en cuanto a tasa de error de bit y throughput encontrando las situaciones particulares donde es preferable usar codificación convolucional sobre la turbocodificación, con el fin de optimizer el uso de recursos computacionales y energéticos de los dispositivos en la red móvil.  

Palabras clave
