Patent ID: 7324606

Claim:
A receiver system comprising: a front end portion that receives and digitizes a data signal having one or more training tones and one or more data tones; and a channel estimator component that utilizes the digitized data signal to provide a partial channel estimate that is combined with at least one other partial channel estimate to provide an aggregated channel estimate, the channel estimator component further comprising a frequency shifter that shifts a spectrum of the average impulse response upon receipt of a data signal to provide N/K time samples to an N/K point Fast Fourier Transform component where N is the number of tones in a data signal and K is the number of partial channel estimates forming a full channel estimate, the N/K point Fast Fourier Transform component providing a partial channel estimate corresponding to the received data signal; and a burst counter that increments a count value on receipt of an incoming data signal, the count value determining which partial channel estimate is updated; wherein the channel estimator component is configured to extract training tones from the data signal and determine an average channel impulse response from the training tones, the average channel impulse response being utilized to determine the partial channel estimate.
