| Abstract(in English) | In this paper, we propose a method for improving the performance of CDMA systems using the Concatenative Complete Complementary Code (CCCC) over fast fading channels. The performance of CDMA system depends on the correlation characteristics of the spreading sequence, and CCCC has ideal correlation-sum characteristics and can operate without multi user interference. Existing systems can recover information with one-tap equalization in multipath environments, but the quality degrades over fast fading channels. In this research, the communication quality is improved by using pilot signals to update and equalize the communication path information. |
