| Abstract(in English) | We use Kumar sequences that have small cross-correlations, and large family size. For the improvement of frequency utilization efficiency the Multi-ary CDMA systems are applied, in which each user is assigned plural sequences. We compared the matched filter receiver with the decorrelating detector receiver in terms of BER characteristics. In case of decorrelating detector receiver, we inserted orthogonal dummy vectors into the pilot response matrix to improve the BER characteristics. It is clarified that the Multi-ary CDMA systems are effective by theoretical studies and computer simulation. |
