Abstract: Example terminal antennas and terminals are provided. The terminal antenna includes a mainboard, a feedpoint disposed on the mainboard, a metal housing, an adjustable apparatus, and at least two adjustable ground points. The mainboard is located on an inner side of the metal housing, the metal housing is electrically connected to the mainboard, and a slot is disposed in the metal housing. The feedpoint and the at least two adjustable ground points each are disposed on a part of the mainboard facing the slot. The at least two adjustable ground points are each electrically connected to the mainboard by the adjustable apparatus, and the adjustable apparatus is configured to control whether each adjustable ground point is grounded.

Abstract: A transmitter, a receiver, and a signal processing method are provided. The transmitter includes a constellation mapper, a signal conversion module, a digital signal processor, and a digital-to-analog converter. The constellation mapper is configured to determine a mapping relationship between a bit stream and a constellation point in a polar coordinate system, and generate a constellation symbol data flow according to the mapping relationship. The signal conversion module is configured to convert the constellation symbol data flow into an amplitude signal and a phase signal, where the amplitude signal is a 2-level analog signal, and the phase signal is an 8-level digital signal. The digital signal processor is configured to perform digital signal processing on the phase signal, to generate a multi-level digital signal. The digital-to-analog converter is configured to convert the multi-level digital signal into a multi-level analog signal.

Abstract: This application discloses a gesture-based manipulation method and a terminal device. The method includes: displaying a target picture, where the target picture includes a virtual object to be manipulated by using a detected gesture or a detected hand action; obtaining F sets of hand images; recognizing locations of hand knuckles on hands in the F sets of hand images based on the F sets of hand images, to obtain spatial locations of F groups of hand knuckles, where spatial locations of any group of hand knuckles are spatial locations of hand knuckles on a hand in a set of hand images, and F is an integer greater than 0; and performing, based on the spatial locations of the F groups of hand knuckles, a control operation corresponding to the spatial locations of the F groups of hand knuckles.

Abstract: A high-rate high-swing drive circuit applied to a silicon photonic modulator is disclosed. The drive circuit is connected to a drive pre-stage circuit and a modulator load. The drive circuit includes at least one output circuit, and the output circuit includes: a first inverter, a first voltage bias module, a second inverter, a second voltage bias module, and an inductor. The drive circuit formed by using such a circuit connection increases an output swing of a drive while ensuring a high rate.

Abstract: This application provides an image display method and device. The method includes: detecting a first operation performed by a user to start an application; displaying a first interface on the display screen in response to the first operation; detecting a second operation performed by the user in the first interface to indicate to shoot an image, or detecting a second operation performed by the user in the first interface to indicate to select an image; and displaying a multi-dimensional model of a target object in the first interface or a second interface in response to the second operation, where the multi-dimensional model is a multi-dimensional model constructed for the target object in a target image collected by the camera or in a selected target image, and model construction parameters required for constructing the multi-dimensional model are model construction parameters that match an object mask corresponding to the target object.
