    In this work, we evaluate the performance of the downlink in a CDMA cellular system with a services mix (voice and high data-rate packet). The users that arrive to the system follow a Poisson process. The data service is WWW traffic and the transmission is made through code aggregation in burst mode. The focus of this work is not only in the performance of data users, but also in the impact on voi... View full abstract»

    This paper presents a study of the performance of an AURORA-based distributed speech recognition system over IEEE 802.11 wireless networks. The recognition features are vector quantized, packetized and sent over a simulated 802.11b network with interfering traffic. At the receiver, error concealment, VQ decoding and recognition are performed. We investigate the influence of the feature encoder, of... View full abstract»
