A method for estimating the channel impulse response of a signal transmission channel and the mobile station

摘要

The invention relates to a method for estimation of an impulse response (h) of a signal transmission channel (1) in a mobile communication system and to a mobile station (15), especially a mobile phone, comprising estimation means for estimation of the impulse response (h) of the signal transmission channel (1) in the mobile communication system. The invention allows a realization of mobile stations for use in a code division multiple access (CDMA) transmission mode and in a time division multiple access (TDMA) transmission mode with less implementation complexity. The estimation means comprises exactly one combined channel estimator (45) . The mobile station (15) receives signals (20) transmitted via the signal transmission channel (1) either in the TDMA transmission mode or in the CDMA transmission mode. The exactly one combined channel estimator (45) estimates the impulse response (h) of the signal transmission channel (1) dependent on the transmission mode.
