Abstract
This paper concerns CDMA cellular networks equipped with conventional matched filter receivers. For this type of cellular networks, both the cell breathing effect and near-far unfair access problem exist. The cell breathing effect is an effect that the cell coverage will shrink when supporting more users. The near-far unfair access problem means that the near users will have a lower blocking probability than far users. To solve these two problems, a bandwidth-space partitioning technique is adopted. Several admission control/subband assignment schemes, based on the bandwidth-space partitioning technique, are proposed for solving the above two problems Author(s) Shih-Tsung Yang Transilica, Inc, San Diego, CA, USA Ephremides, AnthonyKeywords
