Cancelador de eco acústico, lgoritmo de mínimos cuadrados promediados LMS, filtros adaptablesResumen
Este trabajo se centra en el estudio y la comparación de las características de modelado, simulación y desempeño de filtros adaptativos LMS utilizados para aplicaciones de cancelación de eco. En ese sentido, tres algoritmos de filtrado adaptativo
convencionales se revisan, el algoritmo de Mínimos Cuadrados Promediados Convencional (LMS), el algoritmo LMS Normalizado (NLMS) y el algoritmo LMS signado (SLMS). Por último, la comparación entre los algoritmos se evaluó mediante índices de desempeño tales como respuesta temporal, velocidad de convergencia y análisis espectral ERLE.
