Abstract(in English) | This paper proposes a spatial filtering technique to effectively receive narrow angle spread multipath incoming to the typical macrocell basestations in DS/CDMA cellular systems. In the proposed system, a fictional received signal for each antenna element is generated in the receiver using the measured delay profiles and known QPSK symbol sequences, and this signal is employed for antenna weight calculation. At this stager to shape high gain point toward all the desired multipath components in the spatial filter, phase and delay time of the measured delay profiles for the fictional received signal is adjusted to be equal to enhance the generate fictional received signal with inphase. Computer simulation confirms that the proposed algorithm can create effective spatial filter for receiving narrow angle multpath and achieves better performances than the conventional algorithm. |
