Performance of MIMO systems

Performance of MIMO systems

Abstract

Demand in high data rate communications, driven by internet and cellular mobile, have increased, specially in wireless local area networks, emerging home audio visual networks and multimedia services in general. The limitation of the available radio spectrum makes it impossible for the data rate needs to be accomplished by an increase in the bandwidth. The deployment of multiple antennas in the transmitter and the receiver, multiple input multiple output (MIMO), a cost effective technology, makes it feasible to meet the high data rate demands. In this work, several scenarios such as the transmission under Rayleigh and Rice channel conditions are analyzed. Different transmission schemes are used, using different numbers of transmit and receive antennas. The focus of the project is an investigation of the fundamental performance tradeoff between bit error probability and bit rate in these systems, related to the number of antennas deployed and the SNR. ______________________________________________________________ La demanda de la alta velocidad de datos ha crecido considerablemente debido a internet y a los teléfonos móviles especialmente en redes wifi, en las redes audiovisuales de los hogares y servicios multimedia. La limitación del espectro de radio disponible hace imposible que la velocidad de datos aumente aumentando el ancho de banda. El desarrollo de múltiples antenas transmitiendo y múltiples antenas recibiendo, multiple input multiple output (MIMO), tiene un bajo coste y hace factible el aumento de alta velocidad de datos. En el trabajo, varios tipos de de condiciones de transmisión, como los canales Rayleigh y Rice se han analizado. Se han usado diferentes modelos de transmisión, utilizando numerosas antenas en transmisión y recepción. El objetivo del proyecto es la investigación del rendimiento que se obtiene entre sacrificar la probabilidad de bit y la tasa de transmisión en estos sistemas, relacionándolo con el número de antenas en transmisión y recepción y la SNR.
