Power estimation by code signals mime.

Method of estimating energy per code for one or more streams of a received signal of multiple input, multiple output (MIMO) multi-stream, wherein the method comprises: constructing (510) a parametric model for damage signal MIMO received multi-stream, the parametric model omitting the code reuse interference; measuring (520) the covariance or impairment covariance associated data to the MIMO signal received multi-stream; adjusting (530) the parametric model covariance or impairment covariance measurement data for one or more scale parameter values; and calculating (540, 550) a value of energy per code for a first stream of the MIMO signal received multi-stream, depending on the value or values ​​of the parameters of scale.
