Title
Pilot-based non-adaptive equalizers using an array antenna for DTV receivers
Abstract
In this paper, a pilot-based single-input multiple-output (SIMO) minimum mean square error (MMSE) decision feedback equalizer (DFE) using an array antenna is proposed to overcome the long transient period problem of adaptive equalizers for a severely distorted digital television (DTV) channel. Furthermore, for the sake of reduced complexity, a low complexity spatio-temporal equalizer is developed, wherein one spatial equalizer and multiple single input single-output (SISO) MMSE-DFEs are cascaded. To further improve the spatio-temporal equalizer, we also propose an orthogonalization technique of the beamforming weights. Two implementation issues, the channel estimation and computational complexities of the proposed algorithms, are also investigated. The simulation results indicate that the spatio-temporal equalizer has a slightly degraded performance with a much lower complexity than the SIMO MMSE-DFE.
