A analysis of Erlang Capacity for Voice/Data DS-CDMA Systems with the Limited Number of Channel Elements

摘要

In this paper, we propose an analytical pro- cedure for the Erlang capacity in the reverse link of the DS- CDMA systems supporting voice and data services with the lim- ited number of channel elements. Especially, we focus on IS-95B type systems with sectorized directional antenna that support the medium data rates for data traffic by aggregating multiple codes in both direction, to and from the mobile device.
