Abstract(in English) | In this paper, we propose a novel delay-lock loop (DLL) using a code-orthogonalizing filter (COF) which suppresses multiple access interference (MAI) in an asynchronous DS/CDMA. The DLL tracks the chip clock fluctuation of the own pseudo-noise (PN) sequence, however, the clock jitter increases by MAI in DS/CDMA. While, the COF can suppress MAI, however, the effect is degraded when the jitter increases, and bit error rate (BER) performance is degraded. By combining both the circuits, the preferable DLL and COF circuits can be realized A configuration of the proposed system is presented, and performance improvements of jitter and BER are shown. |
