Abstract

See full text

A signal-power related quantity is estimated by repeating a processing step, where measured values of instantaneous signal powers are processed. At each relevant part step of the processing and for each relevant matrix (99), elements (98) that are indicated to be negligibly small are changed to instead be exactly equal to zero. The computational complexity can thereby be decreased considerably. The principles are applied on determination of signal-power related quantities in wireless communications systems.
