Title
(EN) Method for detecting random access signals and base station
(ZH) 一种随机接入信号的检测方法和基站
Abstract
(EN) The invention discloses a method for detecting random access signals and a base station, and relates to the field of mobile communication. The method solves the problem of high false alarm in the process of detecting the random access signals. The method comprises the following steps of: detecting four indexes, namely peak value, designated multiple of the peak value, mean value and pseudo peak value, of each related sequence data fragment of the random access signals; and if the data fragment does not reach one or more indexes, determining that the random access signal detection corresponding to the data fragment fails. According to the technical scheme provided by the invention, the method is suitable for an orthogonal frequency division multiplexing system.
