Abstract: Examples pertaining to measuring the correlation between multiple-input multiple-output (MIMO) antennas in mobile communications are described. A controller measures an over-the-air (OTA) total radiated power (TRP) associated with each of a plurality of transmit precoding matrix indicator (TPMI) indices configured for a communication apparatus to perform single-layer transmissions to obtain a plurality of TRP values each associated with a TPMI index. Each TPMI index indicates a precoding matrix for a single-layer transmission. The controller calculates an envelope correlation coefficient (ECC) between two antennas of the communication apparatus according to the TRP values.

Abstract: A method for aligning test environments is provided. The method inlcudes: measuring, by a measurement device located in an anechoic chamber, a standard signal transmitted from a base station simulator and went through to a channel emulator, then output with noise added inside the channel emulator, to multiple antennas within the anechoic chamber; obtaining, by a computing device, measurement information based on the standard signal and the noise transmitted from the measurement device; determining, by the computing device, whether the measurement information is within a predetermined range of a target value; and transmitting, by the computing device, a control signal to the channel emulator to adjust the noise output from the channel emulator so that the computing device obtains desired measurement information based on the standard signal and the adjusted noise when the measurement information is not within the predetermined range of the target value.

Abstract: The present invention relates to a method for detecting and typing high-risk human papillomavirus (HPV). A probe having a specific detection function for 14 types of high-risk HPV is disclosed, and a technology capable of detecting and typing high-risk HPV DNA is developed on the basis of a nucleic acid hybridization chemiluminescence immunoassay technology.
