A method and an arrangement are provided for generating an estimate of the impulse response of a radio channel. There is generated ( 202, 406 ) an initial estimate of the impulse response of a radio channel, and a signal is equalized ( 203, 407 ) by using the initial estimate. The equalized signal is decoded ( 205, 409 ). There is obtained ( 411 ) feedback information from the signal ( 306 ) after equalization, an updated channel estimate is generated ( 304 412 ) by using said feedback information, and the signal is equalized ( 407 ) again by using said updated channel estimate and said feedback information. |
