    Abstract: A computing device includes a processor and memory storing instructions that are executable to determine a median of a first mixture distribution. The instructions are also executable to determine a parent mean, a parent standard deviation, and boundaries for each of multiple segments in the first mixture distribution. The instructions are also executable to determine a segment mean and a segment second moment for each segment based on the parent mean, the parent standard deviation, and the boundaries for the respective segment. The instructions are also executable to determine a scaled probability for each segment. The instructions are also executable to determine a mixture mean and a mixture standard deviation for the first mixture distribution based on the segment mean, the segment second moment, and the scaled probability for each segment in the first mixture distribution.

    Abstract: A method of associating streams of baseband data with one or more antenna ports of a remote radio head (RRH) is provided. The method includes extracting streams of baseband data from a user-plane of front-haul data communicated to the RRH over a communication link, determining which, if any, layer mapping and precoding scheme and associated antenna port configuration was used to encode and modulate one or more of the extracted streams of baseband data, wherein each layer mapping and precoding scheme has one or more of associated antenna port configurations, each antenna port configuration associating each of one or more steams of baseband data with a respective antenna port of the RRH.

    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。
