Grupo de Tratamiento de Audio y Comunicaciones (GTAC)

Descripción	El Grupo de Tratamiento de Audio y Comunicaciones (GTAC) centra su investigación en algoritmos de tratamiento digital de señal para aplicaciones de sonido y comunicaciones inalámbricas. Desde 1998, los miembros del GTAC han dirigido en diferentes proyectos de investigación dentro del área de Procesado de Audio para sistemas de control activo de ruido, la percepción cualitativa del sonido, la reproducción y análisis de audio espacial y el filtrado de audio multicanal. Mientras que en el área de Comunicaciones Móviles, el trabajo desarrollado se ha centrado en el diseño de receptores MIMO eficientes, y algoritmos para sistemas de comunicaciones multi-usuario y sistemas coordinados. Los resultados alcanzados en estos campos están disponibles a través de los numerosos trabajos que figuran en el menú de publicaciones. En la actualidad, el GTAC está liderando el uso de unidades de procesamiento gráfico de propósito general (GP-GPU) para el procesado multicanal en tiempo real. Los sistemas multicanal son especialmente adecuados para la programación paralela, ya que tienen que procesar varias señales simultáneamente. Las unidades GP-GPU están diseñadas para llevar a cabo la computación masiva en paralelo, pero con restricciones de memoria y programación que deben tenerse en cuenta con el fin de explotar plenamente sus potencialidades. Para ello, el GTAC está colaborando en varios proyectos con el Grupo Interdisciplinar de Computación y Comunicaciones de la Universidad Politécnica de Valencia. El laboratorio del GTAC cuenta con varias instalaciones que incluyen una sala de audio de gran tamaño (40 m2), totalmente equipada con instrumentación audiovisual y de control.
