“…A significant performance difference between the two observed environments can be noticed. The channel spatial diversity effect in the SIC algorithm has already been investigated in [6]. In the diversity case, we verify that the DPA-1 algorithm brings about little throughput improvement in the overloaded region (more packets than antennas), while in the no diversity case, the throughput increase is much more significant.…”

In this work we discuss the use of a dynamic packet to timeslot assignment (DPA) algorithm combined with a non-linear 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, especially for a high offered load condition.
