发明名称 CHANNEL ESTIMATION FOR OFDM SYSTEMS
摘要 <p>The present invention concerns a method for channel estimation for OFDM-based communications. According to the invention, a coarse channel estimate is first obtained from the received signal, after which a single filter is being applied to all available coarse channel estimates. The present invention also concerns a method for channel estimation for OFDM-based communications, which includes obtaining a coarse estimate of the channel transfer factor by removing known pilot subchannel amplitudes from a Fourier- transformed pilot sequence; according to the invention, said pilot sequence is obtained by averaging over at least two repeatedly received preamble OFDM symbols. Application to devices and apparatus implementing these methods.</p>
