Abstract
Method and apparatus employed by a UE for interference signal code power noise variance estimation employing a reduced number of samples utilizing the equation where whereN=L−N·K,where and where As an alternative, a recursive technique may be employed wherein the noise variance is estimated from the ignored coefficients of the estimated channel output and upgraded recursively as per the following: where ĥare the channel estimates after the post processing and the noise variance estimates {circumflex over (σ)}, and the initial values of ĥare all zeros.
