Abstract: Disclosed is a method for estimating database management system performance, in which a performance change ratio of a DBMS can be determined once a first knob group, a second knob group, and a data volume of active data in data managed by the DBMS are obtained, without actually configuring the second knob group in the DBMS, executing a job by the DBMS, and then observing the execution. In other words, the performance change ratio of the DBMS can be estimated without interacting with the DBMS. DBMS security can be ensured, performance measurement approaches are provided for self-tuning and self-management of the DBMS, and reliable and stable running of the DBMS is ensured.

Abstract: This application provides a power adjustment method and apparatus. The method includes obtaining a to-be-output signal, performing first automatic gain control (AGC) processing on the to-be-output signal to obtain the to-be-output signal on which the first AGC processing is performed, and to obtain a gain value of the to-be-output signal. The method also includes performing digital pre-distortion (DPD) processing on the to-be-output signal on which the first AGC processing is performed, to obtain the to-be-output signal on which the DPD processing is performed. The method further includes calculating an output power back-off (OBO) value based on the gain value, adjusting, based on the OBO value, output power of the to-be-output signal on which the DPD processing is performed, and sending, to a signal receive end, the to-be-output signal on which the power adjustment is performed.

Abstract: A signal processing method and a related device are provided. The signal processing method includes: determining that there are N directions for received signals corresponding to a same signal source; configuring beam directions of an antenna as the N directions; estimating delays of the N received signals received by using the antenna, and separately performing, by using the estimated delays of the N received signals, delay compensation on the N received signals to obtain N received signals obtained after delay compensation, where the N received signals are in a one-to-one correspondence with the N directions, and N is an integer greater than 1; and performing combining processing on the N received signals obtained after delay compensation. The technical solutions in embodiments of the present invention help increase a signal reception gain in a multipath scenario.

Abstract: Embodiments of the present invention relate to a display apparatus including: a display layer including a pixel array, a first lens layer, and a second lens layer. The second lens layer is disposed between the first lens layer and the display layer. The first lens layer includes a first lens array, where the first lens array is configured to deflect lights passing through the first lens array in different projection directions, so as to achieve stereoscopic parallax. The second lens layer includes a second lens array, and the second lens array is configured to project beams, emitted from the pixel array, onto the first lens array. A structure of the display apparatus can reduce impact of a phenomenon of crosstalk between pixels of the display apparatus, thereby improving a resolution and a display effect of the display apparatus.
