| Abstract(in English) | In the chaos CDMA, it has been showed that negative autocorrelation and the Gaussian waveform is valid in the time domain spreading codes. Extended CDMA, Gabor Division/Spread Spectrum System (GD/SSS) is proposed which have spreading codes in both of time domain and frequency domain. By both domains spreading, it can be achieved the more robust synchronization system. There are two correlators in GD/SSS in order to achieve synchronization in both domains. They need to have the correlation property with synchronization easily. In this paper, we optimized spreading codes to become the correlation properties which are suitable for the synchronization. We have searched the spreading codes by an approximate method because the combination of the spreading code becomes huge. In results, we show that the correlation properties are improved by using the codes obtained by searching. |
