A method, arrangement (512) and communication receiver (500) for SNIR estimation of a received signal, by: deriving (512A) an estimation of SNIR of the received signal in accordance with the relation, where E represents mean value and r(t) represents the level of the received signal; and correcting (512B, 512C) the estimation to produce a corrected estimation Z based on the relation Z= DOLLAR g(a( )x ,) where alpha represents a correction factor. The estimation may be corrected by calculating the correction factor, retrieving the correction factor from a predetermined table (512B) or retrieving the corrected estimation from a predetermined table. |
