| 摘 要： | 摘要：初始测距是802.16e系统中实现网络初始接入的重要过程。本文针对802.16e协议建立了初始测距信号模型，改进了原有频域检测算法。利用初始测距信号的循环对称性，将基站接收窗口的信号在时域上进行叠加，然后使用一种时频相结合的检测算法。结果表明该算法在检测性能上相对原有算法有着非常大的优势。

| Abstract: | Abstract: Initial Ranging is an important process of initial access network in 802.16e systems. The initial ranging signal model is built, and an improved algorithm is proposed according to the 802.16e systems. First the signal in the receive window is superimposed in the Base station because of the cyclic symmetry of the initial ranging signal,then a time-frequency combined detection algorithm is proposed. The result showed that there is a great advantage in the detection probability. |
