摘要

Method and structure for detection of peaks in the cross correlation in multiple stages to random access preambles in LTE networks in which the detection of the preamble using a probabilistic method with multiple stages to detect the peaks of correlation and ensure a probabili For very low false alarm, as well as high probability of detection.Providing an estimation of the parameter of time alignment of user equipment, employing a method of cross correlation with a sequence of root zadoff - Chu.In the method of the invention is to make a statistical analysis of the signal to determine a set of reference samples, and from that set, perform a statistical test in the samples of the signal cross correlation to decide the presence or absence of correlation peaks.
