Abstract: A method for detecting interference in a wireless system is disclosed. The method includes receiving an uplink signal at a remote radio head in a distributed base station, passing the uplink signal from the remote radio head to a baseband unit over a front-haul communication link as baseband IQ data, and intercepting the baseband IQ data at a tester coupled between the remote radio head and the baseband unit. Processing of the IQ data is performed to determine whether an interfering signal is present in the uplink signal.

Abstract: A system and method for determining the location of a target mobile device in a communications network. A set of mobile devices in proximity to the target mobile device may be determined (210) as a function of a common parameter of information observed by mobile devices in the set. Measurement data may be shared (220) for the set of mobile devices and the target mobile device, and a location of the target mobile device (230) determined as a function of the shared measurement data. This sharing of measurement data may occur amongst the set of mobile devices and the target mobile device or may also occur at a communication network entity.

Abstract: The present disclosure describes systems and methods for identifying a signal that is a product of two or more other signals. In an embodiment, the presence of intermodulation distortion in a communication system is determined by comparing a cyclic autocorrelation function (“CAF”) of a complex envelop of signal content in a frequency bin, comparing the determined CAF with the CAF for a known signal type, and comparing a frequency of the signal content with the frequency of an RF channel in the communication system.

Abstract translation: 本公开描述了用于识别作为两个或更多个其他信号的乘积的信号的系统和方法。 在一个实施例中，通过比较频率仓中的信号内容的复包络的循环自相关函数（“CAF”）来确定通信系统中互调失真的存在，将所确定的CAF与CAF进行比较以获知已知的信号类型 ，并且将通信系统中的信号内容的频率与RF信道的频率进行比较。

Abstract: The present disclosure describes systems and methods for identifying a signal that is a product of two or more other signals. In an embodiment, the presence of a particular signal is determined and identified by applying a cyclostationarity detection technique, such as comparing a cyclic autocorrelation function of a product signal with the cyclic autocorrelation function of at least one of the signals which formed the product signal.
