The method, with low complexity for the synchronization of wireless communication networks

摘要

The present invention relates to a process for the synchronization of a base station of a wireless communication network and a a digital signal from the base station received user device, wherein the digital signal in frames with a fixed frame length, is organized in the time domain and one or more synchronization signals comprises. The synchronization method according to the invention can, for example, in the case of the points and the points - advanced - networks are used and has a reduced complexity, which leads to a reduced energy - and time consumption of the synchronization of a user device leads. The method includes at least the steps of the quantizer of the synchronization signal, notably, in order to obtain a particularly quantized synchronization signal, cross-correlating the particularly quantized synchronization signal down with the sampled digital signal or from the original digital signal, accumulating of the result of this cross correlating and stopping of this cross correlating with or without a special stop criterion.
