    摘要： This specific person detection system: identifies, from among the persons recorded in a specific person recording unit, a person who most closely matches a feature value extracted from image data; calculates the degree to which feature values of a plurality of persons extracted from other image data match the identified person; and outputs, as an identification result, information about a person who has a feature value closely matching the identified person, and who is associated with angle information that most closely matches angle information associated with the identified person.

    摘要： The present invention carries out SISO decoding of a reception signal having a scrambled symbol arrangement using a process having reduced complexity. Coordinates are generated for a reference point obtained not through scrambling and mapping of a symbol reference point position but through scrambling and mapping of a symbol number. This reference point simulates transmission-side scrambling and is generated for each symbol number by a first mapping means. Because the binary expression of a corresponding original signal number is retained, a bit likelihood calculation means can easily calculate a bit likelihood based on the distance between the reference point and a reception signal. The calculated bit likelihood is thereafter deinterleaved and subjected to SISO error-correcting decoding. The thus obtained bit likelihood is then reinterleaved and used to calculate a symbol probability. Soft symbols are generated through the multiplication of all the calculated symbol probabilities by corresponding reference points output by a second mapping means similar to the first mapping means.

    摘要翻译： 本发明使用复杂度降低的处理来执行具有加扰符号排列的接收信号的SISO解码。 针对不通过加扰和映射符号参考点位置而是通过加扰和映射符号编号而获得的参考点来生成坐标。 该参考点模拟传输侧加扰并且由第一映射装置为每个符号编号产生。 因为相应的原始信号数的二进制表达式被保留，所以比特似然性计算装置可以基于参考点和接收信号之间的距离容易地计算比特似然性。 之后计算出的比特似然性被解交织并且经历SISO纠错解码。 然后将这样获得的比特似然性重新传送并用于计算符号概率。 通过将所有计算的符号概率乘以由与第一映射装置类似的第二映射装置输出的对应参考点而生成软符号。
