>Recently I have participated in a workgroup which is do some working and researching on 802.16d and 802.16e. And I am particularly interested in the channel estimation problem of OFDM PHY layer. According to the standards, two special training sequences are provided: the preamble and the pilot. Commonly, the preamble is used to do synchronization and channel estimation. And the pilot is used to do channel state tracking and frequency offset estimation.
>
>So would you like to give me some advice on how to sufficiently use the preamble and pilot to obtain the best channel estimation? I want to know more about the appropriated method of channel estimation and interpolation for 802.16d&e OFDM PHY layer.

>Expect your reply eagerly.
>Thank you very much.
>Yours sincerely,
