ABSTRACT:
Briefly, in accordance with one embodiment of the invention, a channel estimator may be adapted to provide a channel estimate based at least in part on an estimated delay spread. The channel estimator may be adapted to provide a more accurate channel estimation in the event of a lower estimated delay spread. In one embodiment, the channel estimator provides a frequency domain channel estimate, and in another embodiment the channel estimator provides a time domain channel estimate.
