Analysis of Erlang Capacity for the Multimedia DS-CDMA Systems with the Limited Number of Channel Elements

摘要

In practice, the DS-CDMA system is equipped with a finite number of Channel Element (CE) s that performs the baseband spread signal processing for a given channel in the base station. In this situation, the call blocking can be caused not only by the insufficient number of channel elements but also by the limit of available traffic channels. In this paper, we focus on analyzing the effect of the limited number of CEs on the Erlang capacity of multimedia DS-CDMA systems in the reverse link when the CDMA cells are sectorized with 3 sectors.
