Abstract

The invention relates to a method for screening abnormal phase calibration data based on multi-channel consistency, which comprises the following steps of: calculating a phase data difference of adjacent frequency points to obtain a distance difference, and summarizing the distance difference as a data set D; setting a close distance dist; calculating distances among all objects in the data set D; judging the connectivity of edges between the objects, and constructing a generative graph; constructing an adjacent matrix through objects with connectivity; and searching the generated graph, and screening abnormal phase calibration data points. According to the method and the device for screening the abnormal phase calibration data based on the multi-channel consistency, the processor and the computer readable storage medium, the efficiency and the precision degree are high for a large-scale MIMO (Multiple Input Multiple Output) system, and the workload is greatly reduced. According to the method, the phase calibration data is preprocessed, the multi-channel phase consistency of the MIMO equipment is remarkably improved, the concepts of proximity and maximum clique are combined, the method has innovativeness, and abnormal data can be efficiently and accurately screened out.

Description

technical field [0001] The present invention relates to the field of wireless communication equipment, in particular to the field of abnormal data screening, and specifically refers to a method, device, processor and computer-readable storage medium for screening and processing abnormal phase calibration data based on multi-channel consistency. Background technique [0002] In the 5G TDD communication system, the base station performs downlink channel precoding design based on the estimated uplink channel state information (CSI), and serves multiple UEs on the same time-frequency resource based on the reciprocity of uplink and downlink channels. However, in actual communication, only the wireless channel in the air satisfies reciprocity, and a complete communication channel includes not only the wireless channel in the air, but also the radio frequency hardware circuit. For terminals, power mismatch will cause a certain degree of system performance degradation; for base stat...

Problems solved by technology

[0004] After the phase calibration of the MIMO equipment is completed, due to various problems that may occur during the phase calibration process, problematic data may be generated. If it is not screened and used directly in the MIMO equipment, it will lead to errors and make the interoperability of the MIMO equipment Sexual impairment, inefficiency, etc.
