A channel estimation method and apparatus are provided in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. When signals are received from channel paths (M1,M2,M3) of each user, channel impulse responses of each user are estimated by using a single cyclic correlation on as many as a number of channel taps corresponding to a guard period. An estimate value of a tap corresponding to a midamble offset (W) may be masked. Thus, even a channel path that has been further delayed than the midamble offset (W) may be estimated and a channel estimation performance may be enhanced. |
