| Abstract(in English) | Multi-stage serial interference canceller(MSSIC)has a good performance among the interference cancellers in DS-CDMA(Direct Sequence Code Division Multiple Access)system. In MSSIC, when a bit is detected incorrectly, the amplitude of the output residual signal becomes larger than that of the input. By detecting the energy of residual signal, we can estimate the reliability of the detected bits. In this paper, we propose adaptive control method of interference rejection weight control(IRWC)using this reliability. By considering minus value of IRWC, we can reverse the sign of the bit, which is incorrectly detected. Using the computer simulations, we show the proposed system has the BER performance better than the conventional system. |
