| Abstract(in English) | A DS-CDMA system is considered to be an interference limited channel. Therefore, a lot of interference cancellers have been proposed, however, the most was for the base station. This paper has proposed an easy interference cancellation at the terminal equipment and theorical analysis has been done. This receiver removes interference by using the phase information only without knowing the other users' spreading codes. We assume that all the phase of the transmitted signals from the base station is slaved to the pilot signal and its information is broadcasted to all users. At the receiver, simultaneous equations are made according to the number of users and their correlation noises are measured. The equations are solved by the inverse matrix operation with equating the measured data, and the interference element is calculated. With this method, interference noises are reproduced and extracted from the received signal. In this paper, the theorical bit error rate is compared with simulation results. |
