Abstract: A method of a receiver determining the timing of a signal transmitted in a time-slotted manner, the signal comprising a sequence of information which is repeated at a known interval and has at least a known minimum length. The method performs correlation operations between groups of received slots of information, the groups spaced by the known interval. The groups are moved through the received signal, adding and removing slots, to locate a maximum correlation value sum for the group which should correspond to the timing of the slot. The method also can be used to determine a frequency offset at the receiver and/or an initial phase.

Abstract translation: 一种接收机确定以时隙方式发射的信号的定时的方法，所述信号包括以已知间隔重复且具有至少已知最小长度的信息序列。 该方法在接收到的信息时隙的组之间执行相关操作，所述组间隔了已知间隔。 通过接收的信号移动组，添加和移除时隙，以便为应该对应于时隙的定时的组定位最大相关值和。 该方法还可以用于确定接收机处的频率偏移和/或初始相位。
