Abstract

In this paper, we focus on the uplink performances in TDD-CDMA distributed wireless communication system (DWCS). First, the uplink capacity and load factor are analyzed in theory. Then a model is established to estimate interference increase due to a new or handoff user. Next an admission control algorithm is proposed based on the model. The simulation results show that MUD and array element number have a great impact on the performance of the proposed algorithm and the proposed admission control algorithm can promote the system performance effectively if proper noise rise threshold is set.
