SYSTEMS AND METHODS FOR LONG PULSE RADAR CHIRP DETECTOR FOR LTE LICENSED ASSISTED ACCESS DYNAMIC FREQUENCY SELECTION

摘要

According to certain embodiments, a method by a network node for linear chirp detection includes obtaining a first number, N, of samples of a signal. The samples are divided into at least a first group and a second group, where the first group includes a second number, D, of the samples of the signal and the second group includes a third number, N-D, of the samples of the signal. A correlation is performed between the first group of samples and the second group of samples to generate a resultant group of samples of the signal. Within the resultant group of samples, a peak value is identified in the frequency domain. Based on at least one property associated with the peak value, it is determined whether there is a linear chirp within the signal.
