Abstract :
We discuss the use of a dynamic packet to time-slot assignment (DPA) algorithm combined with a nonlinear interference suppression method for a TDMA-based network equipped with an antenna array in the base station. Single and multicell cell scenarios are considered. The whole receiver strategy (combined DPA and non-linear spatial processing) is then evaluated for different degrees of spatial diversity. Results show that the combined strategy produces a considerable throughput improvement, specially for a high offered load condition.
