— An adaptive multi-target space-time down-link receiver for user terminals of WCDMA systems under soft handoff is presented. The receiver consists of M antennas and K array processors, each one followed by a chip-rate equalizer and a despreader. The resulting K signals are combined in an " adaptive ratio com-biner " which is updated by pilot common channel… (More)
— This paper presents an adaptive multi-target space-time architecture for downlink receivers in the user terminal of WCDMA systems under soft handoff. The receiver consists of M antennas and K array processors, each one followed by a chip-rate equalizer and a despreader. The resulting signals from these K branches are combined in an adaptive ratio combiner… (More)
– In the year 2005 the Brazilian government supported many research consortia in order to develop an advanced Digital Television System employing the most recent technologies for multimedia broadcasting. One of the proposals for the physical layer of this system was entitled Innovative Modulation for the Brazilian Digital TV System (MI-SBTVD). The MI-SBTVD… (More)

Long Term Evolution (LTE), a standard developed by the 3rd Generation Partnership Project (3GPP), is currently the 4G mainstream technology, providing technology convergence for this generation of cellular communication systems. LTE networks promise data transmission rates of 100 Mbps in the downlink channel. For this high throughput it needs to optimize… (More)
