Abstract:
A method for processing received signals transmitted via a transmission channel, the method comprising the steps of:obtaining an estimated channel response function (h+e) of said transmission channel, based on said received signals (y), wherein h is an actual channel response function and e is an error vector attributed to the channel; further comprising the steps of: deriving an estimated variance (&dgr;2) of said received signals (y); and modifying said estimated channel response function (h+e) by applying said estimated variance (&dgr;2) to said estimated channel response function (h+e), thereby obtaining a modified impulse response (h); wherein said step of modifying is effected by multiplying said estimated channel response function (h+e) with a vector (a), wherein components of the vector are determined on the basis of parameters of the estimated channel response function (h+e) and said estimated variance (&dgr;2).
