Iterative frequency domain channel estimation for dft-precoded ofdm systems using in-band pilots
We consider two techniques of in-band frequency domain multiplexed (FDM) pilots using interleaved frequency domain multiple access (IFDMA) signal with a Chu sequence for DFT-precod...

Estimation of Time-Variant Channels for OFDM Systems Using Kalman and Wiener Filters
In this paper, two channel estimation schemes for OFDM systems are investigated in a time-variant channel. The orthogonality of the subcarriers is destroyed in a time-variant chann...
