An effect of a DS-SSMA system on narrow-band communication systems using frequency region in common and its rejection method
説明
When a DS-SSMA communication system uses in common the frequency region which narrow-band communication systems have used, the interference power falling on the narrow-band systems from the SS system should be considered. We propose a method that rejects the interference signal component on the transmitting side of the SS system and the transmission signals of the narrow-band systems on the receiving side of the SS system. We clarify the relationship between the signal-to-noise power ratio of the SS system with these band rejection filters and the ratio of narrow bandwidth to the chip rate, and show that prediction error filters are useful to the rejection filters. >
