| Summary: | 碩士 === 輔仁大學 === 電機工程學系碩士班 === 102 === The space–time-block-code (STBC) multiple-input- multiple-output (MIMO) cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) provides a good performance for the multiuser scenario. In this thesis, the channel impulse responses of the space- time-coded MIMO CP-OFDM system are shown to be identifiable up to two ambiguity matrices by subspace channel estimation. The time domain zero-forcing equalizer (ZF)) is used to detect OFDM symbols. Based on the Circular structure of channel matrix, We propose a novel approach to largely increase the number of OFDM symbols. The proposed subspace channel estimation can converge within a small amount of OFDM symbols.
