V. V. S. Nagesh Polu, "Receiver antenna separation over symbol wavelengths in a MIMO-multiuser UWB system with near LOS channels," Master's thesis, Dept. of Electrical and Computer Engineering, University of New Brunswick, (Fredericton, NB, Canada), Jan. 2007.


This thesis investigates the performance of an ultra-wideband (UWB) multiple-input multiple-output (MIMO) multiuser system with near line-of-sight (LOS) channels. Receiver antenna-element separation on the scale of a symbol wavelength ([speed of light]/[symbol rate]) is proposed. Two different antenna array configurations, a two-element linear array and a three-element triangular array, are used for the receiver. UWB indoor LOS channel measurements were made in the 3 to 7 GHz band for these configurations and included in the simulation. Results show that the three-element triangular array performance is significantly improved over the two-element linear array. It is observed from the experimental results that an optimum receiver antenna-element separation of more than four symbol wavelengths is required for a two-by-two case, whereas three symbol wavelengths is sufficient for a three-by-three case.
