The present invention relates to radio channel estimation method applying a modified Minimum Mean Square Error, MMSE, algorithm. The method (30) comprises at first correlating (31) a received signal with a Demodulation Reference Signal, DMRS, sequence for removing impact of a specific DMRS sequence.
