Velocity Estimation Algorithm for a Wireless System
摘要：
A method for estimating the velocity of the Mobile Station (MS) in Orthogonal Frequency Divisional Multiplexing (OFDM)/Orthogonal Frequency Divisional Multiplexing Access (OFDMA) system is disclosed. First, the pilots in the preamble are received by MS and the pilots in a specified symbol of the specific zone are received by MS. An auto-correlation between the received pilots in preamble and the received pilots in the specified symbol of the specific zone is calculated. The auto-correlation is the calculated with frame by frame basis, and the average auto-correlation is calculated from number of frames. Once the average auto-correlation is obtained, the velocity of MS is estimated from predetermined function according to the obtained average auto-correction.
摘要（中）：

公开了一种在正交频分复用（OFDM）/正交频分复用接入（OFDMA）系统中估计移动台（MS）的速度的方法。 首先，前导码中的导频由MS接收，并且特定区域的指定符号中的导频由MS接收。 计算前导码中的接收到的导频与特定区域的指定符号中的接收到的导频之间的自相关。 自相关是逐帧计算的，平均自相关是根据帧数计算的。 一旦获得了平均自相关，则根据获得的平均自动校正从预定函数估计MS的速度。
