Method for generation of training sequence in channel estimation

摘要

The invention discloses a method for generating training sequence in channel estimation. The method, according to a system real working state at a specific time burst, dynamically determines offsets of training sequences selected from a basic code, and the generated user training sequences are allocated to each subscriber at the specific time burst. The method makes said offset as long as possible when dynamically selecting the training sequences. The said system real working state can be the real subscribers number at a specific time burst and/or the channel estimation states of every subscriber before the specific time burst. 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.
