Channel Estimation For Ofdm Systems
Abstract: A device for performing channel estimation in an OFDM system includes a non volatile memory a G matrix selector and a channel estimate generator. The non volatile memory stores a set of G matrices indexed by signal to noise ratio the G matrices being precalculated for a plurality of signal to noise ratios using a fixed Doppler frequency and a fixed delay spread. The G matrix selector uses a quantised signal to noise ratio to select a G matrix from the set of G matrices stored in the non volatile memory. The channel estimate generator multiplies the selected G matrix by LS estimates for the reference signal to obtain a channel estimation.
