A vehicle control system may include a controller that detects an object outside a vehicle, calculates an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle, and updates a phase curve reflecting a phase distortion of an input signal based on the calculated angle.

Vehicle control system for detecting object and method thereof

A received signal DOA estimation method using generation of virtual received signals includes: generating a preset number of virtual antennas at preset positions of a plurality of actual antennas; generating received signals received from the virtual antennas; and generating a DOA estimation value through a DOA estimation algorithm using the received signals received from the virtual antennas and the received signals received from the actual antennas.

Method and apparatus for estimating direction of arrival using generation of virtual received signals

An apparatus for estimating a DOA in a MIMO system includes a receiver and a signal processor. The receiver receives Rx signals from a target through Rx antennas after Tx signals having different phases are transmitted through Tx antennas, and transforms the Rx signals into time domain Rx signals. The processor transforms the time domain Rx signals into Rx signals in a frequency domain including a range-related domain and a velocity-related doppler domain; divides the doppler domain into regions according to a phase difference between the Tx signals; extracts signals from the regions; combines the signals to form first and second arrays; determines a minimum value for each of the first and second arrays using a DML algorithm; selects one of the first and second arrays having the minimum value as a true array; and estimates a DOA corresponding to the true array as an actual DOA of the target.

Provided are a method and an apparatus for transforming coordinates of pixels representing boundary points of an object on a cube map, when pixels respectively correspond to different faces of a cube map. Distances between the boundary pixels may be calculated by using the transformed coordinates. Based on the on the calculated distances, a level of detail (LOD) for texturing the cube map of the pixels may be determined.

Graphics processing employing cube map texturing

A texture processor includes: a texture cache configured to store textures; a controller configured to determine a texture address corresponding to a requested texture among the stored textures and read a texture corresponding to the texture address from the texture cache; a format converter configured to convert a format of the read texture into another format, based on a degree of texture precision required by a graphics processing unit (GPU); and a texture filter configured to perform texture filtering using the read texture having its format converted into the another format.

Texture processing apparatus and method

Provided are a graphics pipeline method and apparatus. For each of plural screen pixels, locations of one or more sampling are determined based on a set pattern to modify an image to be rendered. A pixel corresponding to a set primitive is generated at a determined location of a sampling point, of the one or more sampling points. The image is rendered using the generated pixel.

Graphics pipeline method and apparatus

A texture processing apparatus for performing filtering by using a plurality of textures. A controller is configured to obtain a first texel value from a memory, in which the first texel value is based on a computed first texel offset value. The previously-computed first texel offset value may be used as a second texel offset value to obtain a second texel value of a second texture if a same texture address is input with respect to the first texture and the second texture that are continuously input. A texture filter is configured to perform filtering based on the obtained texel value of the first texture and the texel value of the second texture.
