A method of performing channel estimation includes receiving a frame that includes, for each subcarrier of a subset of subcarriers in the frame, a pair of pilot symbols in the subcarrier. The subcarriers of the subset are regularly spaced apart from one another in the frequency domain. Time-averaged channel estimates for each subcarrier of the subset are generated based on the pairs of pilot symbols. Frequency-averaged channel estimates for respective subcarriers are generated based on the time-averaged channel estimates. Interpolation is performed between respective frequency-averaged channel estimates to generate interpolated channel estimates for subcarriers between the respective subcarriers.
