Abstract

The single-carrier block transmission (SCBT), a.k.a. single-carrier frequency-domain equalization (SC-FDE), is being considered as an option technique for the wireless personal area network (WPAN) operating at 60-GHz. To combat the inter-symbol interference (ISI) in non-line-of-sight (NLOS) environments, the frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion is much more effective than the one based on the zero forcing (ZF) criterion. However, MMSE-FDE needs the estimation of both the channel frequency response (CFR) and the signal-to-noise ratio (SNR). In this work, we estimated CFR and SNR based on the complementary Golay sequences whose sum auto-correlation has a unique peak and zero sidelobe. Through simulations, we proved that the proposed CFR and SNR estimation methods are very effective for SCBT system using MMSE-FDE.
