Abstract: In wired and w ireless OFDM systems, the channel response is obtained by interpolat ion of a piloted coar se est imat ion. Several interpolat ion algo rithms for PSAM OFDM systems ar e discussed; perfo rmance of an FFT -based inter polat ion is evaluated. Finally, some sug gest ions ar e pro posed.

Key words: OFDM, channel estimation, interpolation
