Abstract
A technique for performing channel estimation for a wireless communication channel is provided. A determining circuit determines a channel condition for the wireless communication channel. A filtering circuit applies an estimation filter to reference signals transmitted on the wireless communication channel. The filter estimates coefficients for a subset of Resource Elements transmitted on the wireless communication channel. The subset is chosen depending on the determined channel condition. An interpolating circuit interpolates the estimated coefficients for Resource Elements that are not included in the subset.
