Patent ID: 8520781

Claim:
A method for channel estimation, the method comprising: receiving data at a number of frequency intervals in a frequency band over a number of first time intervals, each frequency interval and each first time interval comprising a portion of the data, and a number of the data portions comprising pilot symbols; identifying a first channel estimate for each pilot symbol within the data over a second time interval comprising at least one first time interval, the first channel estimate comprising a first set of channel estimates; determining a first set of filter coefficients using the first channel estimate, and a noise estimate; generating a second set of channel estimates for each pilot symbol within the data over the second time interval comprising at least one first time interval using the first set of filter coefficients; performing one of time-direction interpolation and frequency-direction interpolation to determine a third set of channel estimates for a number of data portions in a frequency interval using the second set of channel estimates, the frequency interval comprising a data portion comprising a pilot symbol; and performing the other of time-direction interpolation and frequency-direction interpolation to determine a fourth set of channel estimates for each first time interval using at least one of (a) the second set of channel estimates and (b) the third set of channel estimates.
