Open the CIPO recordAbstract From the Canadian patent
Techniques for deriving a high quality channel estimate are described. A first channel impulse response estimate (CIRE) having multiple channel taps is derived, e.g. by filtering initial CIREs obtained from a received pilot. A threshold parameter value is selected based on at least one criterion which , may relate to channel profile, operating SNR number of channel taps, and so , on. A second CIRE is derived by zeroing out selected ones of the channel taps in the first CIRE based on the threshold parameter value. The average energy of the channel taps may be determined, a threshold may be derived based on the average energy and the threshold parameter value and channel taps with …
