Vector-sensor array processing for estimating angles and times of arrival of multipath communication signals
We develop vector-sensor array processing to estimate the angles-of-arrival (AOAs) and time delays of multipath channels in the space-time-polarization domain. A MUSIC-type algorithm for joint angle and delay estimation with a vector-sensor array is derived. Potential applications include multipath channel estimation and mobile localization. Simulation results show that the space-time-polarizat...
متن کاملPropagation Models for Next Generation Networks in NS-3:A Survey
Simulations of mobile radio systems require propagation models for determining the channel characteristics for a given arbitrary scenario. Propagation path loss models can be used to predict wireless channel characteristics like received signal strength, multipath effects, and interference. These predictions are an important aspect of simulation of wireless networks and aid in the high-level ne...
متن کاملThe Effects of Shape Parameterization on the Efficiency of Evolutionary Design Optimization for Viscous Transonic Airfoils
The effect of airfoil shape parameterization on optimum design and its influence on the convergence of the evolutionary optimization process is presented. Three popular airfoil parametric methods including PARSEC, Sobieczky and B-Spline (Bezier curve) are studied and their efficiency and results are compared with those of a new method. The new method takes into consideration the characteristics...
متن کاملImpulse Radio
Impulse radio, a form of ultra-wide band signaling, has properties that make it a viable candidate for short range communications in dense multipath environments. This paper describes the characteristics of impulse radio, gives analytical estimates of its multiple access capability, and presents propagation test results and their implications for the design of the radio receiver.
متن کاملSpatio-temporal diversity in ultra-wideband radio
One of the potential benefits of the UWB radio is its multipath resolution. The implications are multipath components which might not be resolved as distinct arrivals in more narrowband systems, may be separately identified in UWB systems. This paper explores some of the propagation characteristics associated with UWB signals, based on measured data.
