ABSTRACT:
A channel estimation system is disclosed. The channel estimation system comprises a first memory element having a write function and a plurality of read functions, a pilot signal extraction element adapted to receive a first output of the first memory element, a programmable averaging element adapted to receive the output of the pilot signal extraction element, and a combiner adapted to receive a second output of the memory element and the output of the programmable averaging element, wherein the second output of the first memory element is delayed with respect to the first output of the first memory element.
