Abstract(in English) In order to improve spectral efficiency, CDMA overlay, which means co-existence of wideband and narrowband signals in the same frequency band, has been considered. However, signals from existing narrowband systems are not necessarily transmitted with low power level enough not to give damage to DS-CDMA signals. Therefore, an efficient rejection technique for narrowband interferers is required for successful CDMA overlay. Furthermore, it is necessary to cope with sudden changes of interference power levels associated with their appearance/disappearance. In this paper, we propose a canceller to reject such high power narrow-band interference for the DS-CDMA system and show the rejection performance obtained from the computer simulation.
