A&MP - Grup de Processament d'Arrays i Sistemes Multicanal

 

El grup A&MP duu a terme investigació bàsica en tecnologies de capa física per sistemes de comunicacions i treballa sobre diferents esquemes de diversitat (espai, és a dir, múltiples antenes, freqüència, temps o codi) aplicats tant a sistemes d'un com de múltiples usuaris. Les activitats del grup també tenen en compte aspectes de nivell de sistema que puguin beneficiar-se de la interacció amb la capa física. Es consideran tant transmissió per cable com transmissió radio en entorns móvils o satel·lit.

El grupo A&MP lleva a cabo investigación básica en tecnologías de capa física para sistemas de comunicaciones y trabaja sobre diferentes esquemas de diversidad (espacial, es decir, con múltiples antenas, frecuencia, tiempo o código) aplicados tanto a sistemas de uno como de varios usuarios. Las actividades del grupo también tienen en cuenta aspectos a nivel de sistema que pueden beneficiarse de la interacción con la capa física. Se considera tanto transmisión por cable, como transmisión radio en entornos móviles o satélite.

The A&MP group carries out basic research in physical layer technologies that are devoted to communication systems. Different diversity schemes (i.e. spatial with multiple antennas, in frequency, time or code) are applied to either single user or multiple user transmission. Not only physical layer but also PHY/MAC cross-layer research is taken into consideration. Both, wired and wireless (i.e. mobile and satellite) transmission is considered.
