Uplink Throughput in a Single-Macrocell/Single-Microcell CDMA System, With Application to Data Access Points
Overview This paper studies a two-tier CDMA system in which the microcell base is converted into a Data Access Point (DAP), i.e., a limited-range base station that provides high-speed access to one user at a time. The microcell (or DAP) user operates on the same frequency as the macrocell users and has the same chip rate. However, it adapts its spreading factor, and thus its data rate, in accordance with interference conditions. By contrast, the macrocell serves multiple simultaneous data users, each with the same fixed rate. The achievable throughput for individual microcell users is examined and a simple, accurate approximation for its probability distribution is presented.
