Patent ID: 8422607

Claim:
A method of generating channel estimates for processing signals received through first and second transmission channels in a wireless communications network, each channel corresponding to a separate transmit antenna, and each signal comprising a plurality of samples derived from symbols transmitted in the signal, the method comprising: generating a first variable z 1 (k) and a second variable z 2 (k), the first variable being a sequence of values, each k-th value being a function of the 2k-th and 2k+1-th samples and the complex conjugate of a symbol S, the second variable being a sequence of values each k-th value being a function of the 2k-th and 2k+1-th samples, the sign of the 2k-th and 2k+1-th symbols transmitted on one of the antennas and the complex conjugate of the symbol S; and providing a set of filter coefficients {w(l)} l=−L 1 L 2 and generating first and second channel estimates using the first and second variables and the set of filter coefficients.
