Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
OFDM systems is very important when it is used in mobile communication field. Presented the performance simulation to this improved algorithm and then analyzed the simulation results. Analyzed the one-dimensional channel estimation method of cascade. An improved channel estimation method based on FFT had been adopted by windowing. And the new channel estimation method based on DCT is proposed.
