| Abstract(in English) | In Code-Division-Multiple-Access, it is quite common to use Gold-Sequence-Code which is a linear combination of M-sequence Code. In this note, instead of M-sequence generator devise, we construct a Physical-Random Number Generator, and from this devise, we can obtain Physical-Sequence Code and these two Sequence-Code are used for Spectral-Spreading for human voice signals. We embed digital watermark in audio signals by the method of Takano and Nagasaka [8], and digital watermarks are encrypted by usual RSA crypt system and also, use Error-Correcting code for Audio Data Processing. From our simulation study, Gold-Code-Sequences based on random number generator are superior from SNR. |
