Abstract

The present invention provides a channel estimation method and apparatus for use in a mobile communication system receiver. The method and apparatus uses a transmission signal with special structure as provided in the present invention, to estimate channel parameters. The transmission signal according to the present invention comprises a burst. The burst comprises multiple training sequence segments and multiple data segments arranged alternately. Compared with conventional burst structure that only includes a single training sequence segment, this novel burst structure can fully reflect the characteristics of channel change experienced during the communication procedure of the whole burst. According to the method and apparatus for estimating channel parameters in the present invention, flexible combination processing can be performed on the multiple training sequence segments in the received burst according to the channel change mode caused by the receiver's mobility, to obtain the channel parameters for satisfying different CCT requirements and restoring data correctly. Therefore, it overcomes the limitation on the length of the burst caused by the CCT of the channel fading change caused by the mobility of the receiver and thus improves the overall performance of the communication system effectively.
