Method for mitigating interference and interference mitigating receiver

A method for mitigating interference, the method comprising:

• receiving a first signal comprising a first plurality of multipath transmissions from at least one radio cell at a first antenna port and a second signal comprising a second plurality of multipath transmissions from the at least one radio cell at a second antenna port;
• generating a first spatial component of a first channel coefficient based on the first signal and a second spatial component of the first channel coefficient based on the second signal;
• generating a covariance measure based on the first signal and the second signal;
• and
• generating a first spatial component of a first weight for interference mitigation based on the covariance measure, the first spatial component and the second spatial component of the first channel coefficient and a scalar correction value.
