| Abstract(in English) | Recently,Spread-Spectrum techniques have attracted considerable attention in mobile communications because of the anti- interference,random access capability and potential of increasing capacity.To exploit the advantages,however,the receiver must be able to synchronize the locally generated pseudonoise(PN)code with the received one.Under the multipath fading channels,a conventional DLL has problems of jitter performance degradation, lock-off and delay offset.It is necessary to solve these problems, because mobile communications have increased drastically.In this paper we present a new tracking scheme using a canceller of the effect of delay path.Our proposed scheme generates replica of the received signals employing estimated delay error and LMS algorithm, and rejects undesired signals.The good performance of this system is confirmed by computer simulations. |
