Erlang Capacity of Voice/Data DS-CDMA Systems with Prioritized Services

摘要

In this paper, we propose a Call Admission Control (CAC) scheme for the Direct sequence-Code Division Multiple Access (DS-CDMA) systems supporting voice and data Services and analyze the Erlang capacity under the proposed CAC Scheme. Service groups are classified by Quality of Service (QoS) Requirements such a the required Bit Error Rate (BER) and in- Formation bit rate, and Grade of Service (GoS) requirement such As required call blocking probability.
