    摘要: In the mobile communication, a distortion compensation amplifying apparatus is provided. In a predistortion-type distortion compensation amplifying apparatus (9), a signal amplitude change processing unit (10) comprises an odd-power component calculating unit (14) extracting a power component of odd order of an amplitude quantity contained in a signal to be transmitted and outputting it, a coefficient information outputting unit (15) being operable to select one of plural pieces of coefficient information based on a signal from the outside and output it, a multiplying unit (16) multiplying a signal outputted from the odd-power component calculating unit (14) by coefficient information from the coefficient information outputting unit (15) and outputting an attenuation signal, and an adding unit (17) subtracting the attenuation signal from the signal to be transmitted and outputting a result, thereby making an amplifier operate within a range not exceeding a saturation region thereof, decreasing a spurious signal, decreasing an adjacent channel power, and enabling distortion compensating operation even if a frequency of reference to the memory is decreased.

    摘要: Method and apparatus for implementing cell-animation-looking colors as an example of non-photo-realistic rendering in three-dimensional model plot processing. Perspective transformations and light source calculations are carried out for a polygon of the three-dimensional model. Then, the luminosity of each apex of the polygon is calculated. In addition, the color for plotting the polygon is calculated for each of the luminosity ranges defined in advance. Alternatively, the colors for plotting may be calculated and stored in advance. Then, one of the luminosity range is selected from the luminosity ranges defined in advance. If the luminosity range of each pixel inside the polygon lies within the luminosity range selected, the pixel is plotted in the color for plotting corresponding to the luminosity range selected. By repeatedly performing these operations, a cell-animation-looking image is generated.

    摘要: In an equalizer arranged in a wireless communication device: information on correlation in one or more first wireless signals is generated; a channel vector is generated on the basis of the one or more first wireless signals; an extended correlation matrix which contains a correlation matrix indicating the information on correlation and is extended so as to become a circulant matrix is generated; an extended channel vector is generated by extending the channel vector so that the extended channel vector contains elements of the channel vector and has rows the number of which is identical to the number of rows of the extended correlation matrix; and weight coefficients are calculated as a solution, in the frequency domain, of an equation expressed by the extended correlation matrix and the extended channel vector, where the solution is obtained by solving the equation.
