摘要
针对WCDMA中不同信道估计方法进行了研究,对使用不同导频符号长度在不同瑞利衰落环境下对系统性能的影响进行了仿真,发现了用于信道估计的导频符号长度与移动台速率之间的一些规律。
This paper makes a study of different channel＇s estimations in WCDMA. Simulation of the system in which pilot＇s length are different is performed in different rayleigh rading environments. Some relations are found between the length of the pilot and the mobile station＇s velocity.
