In this paper we present the tests and performance evaluations carried out on the modulation system for the terrestrial digital television system (MI-SBTVD). All the results were obtained using computer simulated models, portraying relevant operating scenarios based on well-established channel models. The results obtained in this work have allowed us to(More)
Most of the techniques for multiple access interference (MAI) reduction in code-division multiple access (CDMA) systems are applicable to the uplink, where the base-station knows the signature of all users and can apply a multi-user detection (MUD) strategy. A technique is proposed here to reduce the influence of MAI on the downlink of a multi-carrier CDMA(More)
