Optimal Training Sequence for Space-Time Block Coded Systems in Frequency-Selective Fading Channels

摘要

In this paper, we propose a training sequencernbased space-time block coding (STBC) system for single carrierrntransmission in frequency-selective fading channels. Optimalrntraining sequences, which are used for the channel estimation, arernconstructed in both the time and frequency domains. It is shownrnthat once the channel information is available at the receiver, thisrnsystem is able to achieve both multipath gain and diversity gain.
