Patent ID: 7859990

Claim:
A method of channel estimation in a wireless communication system, the method comprising: receiving a plurality of signal frames from a plurality of base stations in the wireless communication system, each of the plurality of signal frames comprising at least a first zone and a second zone, wherein the first zone comprises a group of unicast symbols and a preamble, the second zone comprises a group of broadcast symbols, and wherein the plurality of base stations transmit a different signal on the first zone, and wherein at least two base stations of the plurality of base stations transmit a signal on the second zone that are exactly identical in nature; determining two or more first delay profiles corresponding to two or more base stations of the plurality of base stations, the two or more first delay profiles being determined using the first zone, each of the two or more first delay profiles being one of a power delay profile and a tap delay profile; and detecting at least one aliased tap in a time domain channel response of the second zone using the two or more first delay profiles.
