Patent ID: 7929645

Claim:
A computer-implemented method of interpolating pilot positions to estimate a channel of a wireless communication receiver, the computer-implemented method comprising: estimating pilot position i+3 of a current symbol as a weighted average of pilot position i+3 of a symbol having an index that is smaller than the current symbol's index by one and pilot position i+3 of a symbol having an index that is greater than the current symbol's index by one; wherein i refers to a pilot position of a symbol and is defined as i=3*(l mod 4)+12n, wherein l defines a symbol's index and wherein n is an integer greater than or equal to zero; estimating pilot position i+6 of a current symbol as a weighted average of pilot position i+9 of a symbol having an index that is smaller than the current symbol's index by one and pilot position i+3 of a symbol having an index that is greater than the current symbol's index by one; and estimating pilot position i+9 of a current symbol as a weighted average of pilot position i+9 of a symbol having an index that is smaller than the current symbol's index by one and pilot position i+9 of a symbol having an index that is greater than the current symbol's index by 1.
