| Abstract(in English) | In this paper, we propose a novel composite circuit of a PLL which operates for carrier synchronization and a code-orthogonalizing (COF) filter which suppresses multiple access interferences in DS/CDMA on a fading environment. The PLL tracks the carrier phase fluctuation of the own signal. The COF forms the tap weight coefficients adaptively to suppress interferences and to extract the own signal. By combining the both circuits, the PLL can improve the carrier phase tracking performance by the signal in which the interferences are suppressed, and the tap weight coefficients of the COF can be calculated easily by carrier synchronization. The proposed system is compared with a conventional system using a COF, and the effects are shown. |
