Claim Text:
1. A method of channel estimation in a receiver used in a wireless communication system, the method comprising: identifying, by one or more processors of the receiver, reference information for a received signal; deriving, by the one or more processors, a channel correlation estimate from the reference information; determining, by the one or more processors from the derived channel correlation estimate, a size of a subset of reference information subcarriers to be used for channel estimation of a given data subcarrier, the subset being fewer than all of the reference information subcarriers associated with the received signal; estimating, by the one or more processors, a localized Signal-to-Interference and Noise Ratio (SINR) over the subset of the reference information subcarriers; and performing, by the one or more processors, channel estimation for the given data subcarrier using the channel correlation estimate and the estimated localized SINR, the channel estimation being applicable to data demodulation of the received signal.
