Pilot-based non-adaptive equalizers using an array antenna for DTV receiver systems

In this paper, a pilot-based single-input multiple-output MMSE decision feedback equalizer (MMSE-DFE) is proposed to overcome the long transient period problem of the adaptive equalizers for the DTV channel. Furthermore, to reduce its complexity, a two-dimensional equalizer is developed, wherein the spatial equalizer and the multiple single-input single-output MMSE-DFEs are optimally combined. Its performance is demonstrated through Monte-Carlo simulation and two implementation issues - the channel estimation and computational complexities - are investigated.
