Abstract :
The capacity of WCDMA network is the critical parameter as it is conditioned with numerous facts. Using SDMA techniques combined with adaptive antenna processing algorithms overall capacity and availability could be significantly increased. Especially the SDMA re-use functionality usage contributes to increasing capacity of (W)CDMA network keeping the multiple access interference reduced. In this paper SDMA re-use functionality is described and the method for performing user allocation / identification in WCDMA systems is suggested as it is recognized as the ldquoproblemrdquo. Possible solution is in making the triplets of distance-angle-velocity data beside re-using resources time-frequency-code.
