Generalized Dynamic Channel Allocation for TD-SCDMA Systems

This paper proposes a generalized version of a dynamic channel allocation (DCA) algorithm for a TD-SCDMA system, which is adaptive to aspects of the steadily varying communication environment such as user distribution, channel allocation of adjacent cells, channel condition, and so on. It aims to fully utilize the physical resource available in the time-division duplexing (TDD) system subject to the various types of inter-cell and intra-cell interference. The simulation results have shown that the proposed DCA scheme improves the outage performance while reducing the average system interference, allowing for full utilization of the physical resource over a wide range of acceptable outage performance.
