• 論文の詳細を見る

• In this paper, we propose a quasi-optimum multiuser detector using co-channel interference cancellation technique in an asynchronous code-division multiple-access communication system, and evaluate its performance by computer simulations. In the proposed detector, maximum likelihood sequence estimation is performed to compare the original received signal with replicas of the signal which are produced from the demodulation data bit sequence of a co-channel interference canceller. In several conditions, the proposed detector is compared with the co-channel interference canceller, and it is shown that the average bit error rate characteristics of the proposed detector are improved considerably.
