摘要 TD-SCDMA系统中的信道估计技术对整个系统的实现具有至关重要的作用,是后续基带算法实现的关键。如果信道估计算法太复杂和不够准确都将对后面的算法实现产生不利影响。论述了TD-SCDMA系统中训练序列的构成,并结合联合检测算法分析了基于训练序列的信道估计所产生的效果。 In TD- SCDMA system,channel estimation is vital to the implement of the system,and it is key to the implement of algorithms behind. If the channel estimate algorithm is too complicated and inaccurate,it must be a bad influence to the later algorithms. In this paper, the construct of training sequence in TD - SCDMA is described and the performance of channel estimate algorithm which uses training sequence is analyzed with joint detection algorithm.
