ABSTRACT:
The embodiments of the present invention discloses a method for generating training sequence in channel estimation, including dynamically determining the length of the channel impulse response of each subscriber respectively according to a real number of subscribers at a specific time burst and/or a channel estimation state of each subscriber prior to a specific time burst; generating a training sequence for each subscriber respectively from a basic code according to the length of the channel impulse response of each subscriber; and allocating the training sequence to each subscriber at the specific time burst. The embodiments of the invention can obtain better effect of channel estimation, thereby decreasing code error rate, enhancing quality of receiving signal in the system and improving communication performance.
