On equalizer tap and antenna selection for UWB and MIMO systems with linear MMSE receivers

The research work in this dissertation addresses reduced complexity equalization technique for multipath channels with large delay spread. This has been one of the key challenges for high data rate impulse radio based Ultra-Wideband (UWB) communication systems using low cost receiver design. Our research focus is on developing efficient and effective tap selection techniques for non-uniformly spaced Minimum Mean Squared Error (MMSE) equalization and applying it to UWB systems to achieve high performance with reduced receiver complexity. Moreover, antenna selection techniques for Multiple Input Multiple Output (MIMO) systems are also explored in our research work.DOCTOR OF PHILOSOPHY (SCE
