Abstract
A receiving device and method for operating a communication system is provided. The receiving device receives a predetermined pilot sequence. The received pilot sequence is converted into at least one frequency domain pilot sequence. A plurality of time invariant channel estimates are determined from the frequency domain pilot sequence. The pilot sequence may include a null cyclic prefix. A time variant channel estimate may be determined from the time invariant channel estimates.
