Abstract
The present invention proposes a device for processing received signals (y) having been transmitted via a transmission channel ( ), comprising: estimation means ( ) adapted to obtain an estimated impulse response function (h ) of said channel ( ) based on said received signals (y) which are received at a first time; derivation means ( ) adapted to derive history information (win ) based on at least one previously estimated impulse response function, calculation means ( ) adapted to calculate modifying information (mwin ) on the basis of said history information (win ), and modification means ( ) adapted to modify said estimated impulse response function (h ) of said channel ( ) obtained on the basis of said received signals (y), by applying said modifying information (mwin ) to said estimated impulse response function (h ) of said channel obtained on the basis of said received signals (y), and adapted to output a modified impulse response function (hm ). The present invention also proposes a corresponding method.
