Abstract :
This paper presents a technique for measuring and modeling multipath components in wideband vector channels. The technique is useful for analyzing and simulating channels for wideband receiver antenna array systems and wideband MIMO (multiple-input, multiple-output) systems. By performing wideband vector channel measurements, the strengths of the multipath components resolved within the bandwidth of the system are compared across the array. Diffuse scattering and summation of multipath with delay differences within the resolution of the receiver cause received multipath components to fade. Fading of components across the array can be compared and quantified using correlation coefficients. Developed through this research is a method of processing data that produces results useful for modeling, simulation, and characterization of wideband vector channels using measurements.
