Abstract:
An estimator (111) is configured to estimate an initial representation of the channel based on the reference signal. A first transformer (112) is configured to transform the initial channel representation into a first domain suitable for suppression of a first type of disturbance. A first suppressor (113) is configured to perform suppression of the first type of disturbance in the first domain for obtaining a first suppressed channel representation. A second transformer (114) is configured to transform the first suppressed channel representation into a second domain suitable for suppression of a second type of disturbance. A second suppressor (115) is configured to perform suppression of the second type of disturbance in the second domain for obtaining a second suppressed channel representation. The first type of disturbance includes one of inter-channel interference and noise, and the second type of disturbance includes the other one of inter-channel interference and noise.
