ABSTRACT:
A method includes generating a plurality of noise-averaged channel estimates using noisy channel estimates. At least some of the noise-averaged channel estimates are generated using different averaging lengths. The method also includes selecting one of the averaging lengths based on the plurality of noise-averaged channel estimates. The step of selecting one of the averaging lengths may include subtracting the noise-averaged channel estimates from the noisy channel estimates to produce a plurality of noise-averaged differences and determining powers of the noise-averaged differences. The step of selecting one of the averaging lengths may also include determining total error powers associated with the different averaging lengths using the powers of the noise-averaged differences and selecting the averaging length corresponding to a lowest total error power.
