Abstract
A channel estimator for a wireless network receiver. The channel estimator includes a plurality of first circuits, each of the plurality of first circuits configured to multiply a respective channel estimate by a corresponding frequency domain signal, wherein the channel estimates correspond to an orthogonal frequency division multiplexing signal received by the wireless network receiver. A second circuit is configured to output a sum of results of multiplying the respective channel estimates by the corresponding frequency domain signals. A third circuit is configured to calculate, based on the sum, a correction factor, wherein the correction factor corresponds to a complex number representation of the respective channel estimates. A fourth circuit is configured to output, based on the correction factor and a previously calculated channel estimate, an updated channel estimate corresponding to the orthogonal frequency division multiplexing signal received by the wireless network receiver.
