Abstract(in English) | Frequency deviation by the Doppler shift in the multipath environment deteriorates the demodulation accuracy significantly. In this paper, we introduce the recursive least squares (RLS) algorithm which is one of the adaptive algorithms for MIMO detector of multiple-input multiple-output - orthogonal frequency division multiplexing (MIMO-OFDM) systems and propose a channel estimation method which has a Doppler resistance. In addition, we focus on the preamble structure of transmission frames to improve further demodulation accuracy. As a result, we report that the channel estimation accuracy is improved utilizing the extension high throughput - long training field (HT-LTF). |
