発明の名称 (英語) COMMUNICATION METHOD AND COMMUNICATION DEVICE UPDATE
発明の概要(英語) A communication method using almost periodic function codes includes using, for modulation, a number of almost periodic function codes, among K almost periodic function codes, that corresponds to the number of users or the number of channels. When it is assumed that k is an integer from 1 to K and an identifier for identifying K almost periodic function codes, a parameter that determines each of the K almost periodic function codes is expressed by δ+(k-1)/K. K is N or 2N (N is the code length of almost periodic function codes). δ is a real number larger than 0 and less than 1/N.
従来技術、競合技術の概要(英語) BACKGROUND ART
Generally the periodic function, a Fourier series expansion can be obtained by generalization. Generally the periodic function, for example, the first m prime numbers p (m) the sum of the square of the frequency 1/2 is configured as a signal. Such a signal may be, did not used in the communication, the non-patent document 1, the application of the proposed communication to the first time.
Non-Patent Document 1 is, generally based on the periodic function (generally a periodic function code) code using a multiple access communication is disclosed. It should be noted that, in Non-Patent Document 1, generally based on the reference periodic function, the spread code cycle is generally: (Almost Periodic Spreading Sequence) is called the APSS.
