Abstract: Disclosed are a bus parking allocation method and apparatus considering operational preferences. The method includes: obtaining a bus station dataset, a parking lot dataset, a bus information dataset, and a bus departure/return dataset; obtaining a distance dataset containing distances between bus stations and parking lots; building a parking allocation model considering operational preferences; building an objective function of the parking allocation model, where one group of buses are allocated to one group of parking lots, with each bus being allocated to at most one parking lot, and the number of buses parked in each parking lot is less than or equal to a capacity of the parking lot; building bus preference lists and parking lot preference lists, and calculating the objective function while satisfying the preference lists, to minimize total parking costs of all buses, thereby obtaining parking allocation results considering operational preferences; and designing multiple visualization views for display.

Abstract: This application relates to the field of communications technologies, and in particular, to a digital predistortion processing method and apparatus. This application provides a digital predistortion processing method and apparatus. Digital predistortion processing of a multichannel power amplifier is supported through deprecoding processing by using one feedback link and one digital predistortion processor. In addition, after being amplified by a power amplifier, a precoded signal is fed back to the feedback link for predistortion parameter calculation, to improve quality of a transmit signal. The digital predistortion processing method and apparatus that are provided in embodiments of this application are intended to improve output linearity and efficiency of a multi-transmit-channel power amplifier while reducing implementation costs and complexity of a transmit device, and further improve overall system performance.

Abstract: An electronic device includes a main body and a cover. The main body includes a front surface with a display disposed thereon, a rear surface, a bottom surface, a top surface, and two opposite lateral surfaces. Each lateral surface defines a sliding slot extending substantially from the center of the lateral surface towards the bottom surface. The cover includes a cover portion and two connecting portions. The two connecting portions are located at two ends of the cover portion spatially corresponding to the sliding slots. The connecting portion includes a supporting portion and a latching portion. The supporting portion protrudes substantially perpendicularly from the cover portion. The latching portion extends into the sliding slot from the free end of the supporting portion and slidably latches with the sliding slot.
