On the performance of a joint TDD CDMA/PRMA and CDMA/ALOHA protocols with 2D RAKE receivers in single-cell and multi-cell networks

摘要

In this paper, we investigate the impact of 2D RAKE receiver on the performance of time division code division multiple access/packet reservation multiple access (TD-CDMA/PRMA) and slotted TD-CDMA/ALOHA uplink medium access control protocols for packet voice transmission in single and multi-cell networks. Simulation results show that the dependence of 2D RAKE receiver performance on the spatial-temporal channel characteristics indicates the necessity to include dynamic scheduling schemes in order to avoid designing the system considering worst case performance.
