Near-optimal states estimation in dynamic systems with Gaussian noise has been extensively applied in research using Kalman filtering (KF). This method is especially useful in technological applications that use noisy data from several sensors or need the estimation of an optimal state vector in systems with multiple observations. A particular situation is that in which some constraints are applied...
In recent years, communications systems through mains, known as PLC (Powerline Communication), have received a lot of interest as part of intelligent networks or smart grids, as well as for multimedia applications at homes. In broadband PLC, systems using multicarrier modulations allow the mitigation of selective frequency fading in the channel. Nevertheless, these modulations require accurate time...
in this contribution, a new room-temperature terahertz source is proposed for overcoming the power limitations inherent to photomixer-based generators. Specifically, a manufactured vertical “large area emitters” is described and analyzed by proposing a Hertzian dipole array model. An estimation of its radiation pattern is included and will be compared with experimental measurements.
Ultra-Wideband (UWB) has a high interest in research and industry for accurate indoor positioning. This technology comprises signals with a bandwidth of at least 500 MHz at a power decay of −10dB. This large bandwidth con-feres the capability of resolving multipath, penetrating through obstacles and accurate ranging. However, NLOS (Non-Line-Of-Sight) conditions produced by obstacles in indoor environments...
