摘要
A method for updating channel estimates in an orthogonal frequency division multiplexing receiver of a wireless local area network includes generating channel estimates for an orthogonal frequency division multiplexing subcarrier as a function of subcarrier index values. The method includes generating a complex number by summing a product of frequency domain signals and the channel estimates for each of the subcarrier index values and dividing the sum by a sum of a squared absolute value of the channel estimate for each of the subcarrier index values. The method includes multiplying the complex number by the channel estimates to generate updated channel estimates.
