Abstract :
A dynamic cell configuration (DCC) scheme has been proposed to reduce the performance degradation due to the nonuniform traffic distribution in CDMA microcellular communication systems employing a circuit switched architecture. In this paper, we discuss the DCC scheme for the common channel communications in the uplink channels of CDMA microcellular system with nonuniform traffic distribution. Then, we propose the DCC scheme with the system control based on the estimated channel load at each base station. The results of computer simulations show that the proposed scheme improves the system performance compared with the system without DCC scheme.
