Patent ID: 8520747

Claim:
A method for channel estimating in a wireless communications network, comprising: detecting existence of interference on one or more OFDM symbol-tone portions of a received signal; estimating one or more channels based at least in part on the detection of one or more interfered OFDM symbol-tone portions of the received signal; and combining non-interfered OFDM symbol-tone portions of the received signal into one or more subsets based at least in part on the interfered portions, wherein the one or more channels are estimated by assigning a first weight to the one or more interfered portions and a second weight to the one or more subsets based at least in part on inferring a likelihood of interference, the first weight being less than the second weight, wherein the received signal comprises at least one OFDM symbol and the interfered portions are one or more outlying tones of the OFDM symbol detected upon comparing the tones of the OFDM symbol to each other.
